Abstract ：
Developing dual-function materials with efficient electromagnetic wave absorption and good thermal conductivity to achieve excellent packaging of devices has considerable appeal in modern electronic devices. Co-MOF74 derivatives/polyacrylamide bifunctional gels (PAM-x) were synthesized by magnetic field assisted technique and in situ radical polymerization. PAM-x showed a minimum reflection loss (RLmin) of-51.6 dB and a maximum effective absorption bandwidth (EAB) of 5.73 GHz at a low filler loading of 5 wt%. The magnetic nanoparticles in the MOF derivatives orient the fillers in the polymer matrix under the action of the magnetic field to form an ordered thermal conductivity path, which improves the thermal conductivity perpendicular to the plane direction and helps to promote rapid heat transfer. This work highlights the potential of MOF derivatives/polymers as bifunctional gels, and also provides a reference for the trade-off between electromagnetic wave absorption and thermal conductivity.

Abstract ：
Removal of hetero ions from the hydrogen peroxide solution is a crucial step in purifying electronic-grade H2O2. Conventional adsorption materials are challenged to meet the need for the simultaneous adsorption of both anions and cations in solvents. UiO-66 (Zr) modified by acetic acid and amino group for simultaneous adsorption of phosphate and Pb2+ in H2O2 purification was fabricated in this work. The as-prepared defective UiO-66-NH2 (Zr) demonstrated a significant increase in specific surface area and porosity, along with more exposed sites for phosphate and Pb2+ adsorption. The adsorption capacity of De-UiO-66-NH2 for phosphate and Pb2+ in H2O2 solution was 52.28 mg g(-1) and 35.4 mg g(-1), which is 1.19 times and 1.88 times that of unmodified UiO-66 (Zr), respectively. The trace simultaneous adsorption with both 100 ppb phosphate and Pb2+ showed removal rates of 94.0% and 88.7%, respectively, confirming the practicality of MOF materials in the purification of electronic chemicals. This work highlights the potential of Zr-based MOFs as anionic and cationic simultaneous adsorbents for highly efficient purification of electronic-grade solvents.

Abstract ：
Excessive electric field strength causes the droplets to contact but not coalesce, severely deteriorating the oil-water separation efficiency. The investigation of the non-coalescence of nonidentical droplets in oil under a DC electric field is conducted using high-speed photography. The effects of droplet volume ratio and interfacial tension ratio on the characteristics and critical parameters for droplet non-coalescence are systematically explored. The results show the critical electrocapillary number for the non-coalescence of nonidentical droplets and critical contact cone angle decreases as the volume sum increases or the interfacial tension ratio decreases, which is related to the competition between the resultant electric field force and the interfacial tension force. These results contribute to optimizing the operating parameters of the electric coalescer and improving the oil-water separation efficiency.

Abstract ：
Vesicles obtained by the self-assembly of asymmetric tetrablock copolymers are a class of materials with fascinating properties. However, simple strategies to synthesize asymmetric tetrablock copolymers are limited. Herein, we have designed and synthesized an initiator which generates radicals by either heating or photoirradiation. Taking the advantages of organocatalyzed reversible complexation mediated radical polymerization which has lower energy requirements, milder reaction conditions, and reduced generation of hazardous byproducts, a three steps synthetic route following “photo-photo-thermal” initiation condition for the preparation of asymmetric CABC tetrablock copolymers with controllable molecular weight, precise block composition and low polydispersity was developed. © 2023 Fudan University

Abstract ：
Due to its excellent spatiotemporal control and benign reaction conditions, photoelectron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization has received a lot of attention. In this study, TAPPY-DTDD-CMP was created and used as a photocatalyst for non-deoxygenated PET-RAFT polymerization under visible light irradiation, producing polymethacrylates with adjustable molecular weight and narrow molecular weight distribution. The effects of the dosages of the catalyst, electron sacrificial agents, and different light sources were carefully examined in the polymerization process. To explore deeper into the underlying mechanism of the tolerance of the polymerization to oxygen, oxygen monitoring studies were also conducted. In addition to allowing the RAFT process to effectively use light and be light-dependent, TAPPY-DTDD-CMP also demonstrates good controllability and adaptability toward different monomers. High catalytic efficiency, stability, reusability, and the capacity to design its structure at the atomic level are further benefits of TAPPY-DTDD-CMP. The range of non-deoxygenated photocatalysts suited for PET-RAFT process conditions is expanded overall by TAPPY-DTDD-CMP. A novel pyrene-based heterogeneous conjugated microporous polymer photocatalyst can mediate oxygen-tolerant PET-RAFT polymerization without prior deoxygenation.

Abstract ：
This study proposes utilizing thermosensitive surfactants, referred to as "environmentally responsive surfactants," as emulsifiers for addressing the complexity of demulsification and separation processes after emulsion polymerization reactions. A series of polyethylene glycol-poly(N-isopropylacrylamide) (PEG-b-PNIPAM) block copolymers with various degrees of polymerization were synthesized via atom transfer radical polymerization (ATRP). The PNIPAM segments within the copolymers exhibit thermosensitive behavior, possessing a lower critical solution temperature (LCST) at 32 degrees C, enabling the control of hydrogen bond formation and rupture with water molecules based on temperature variations. Consequently, the PEG-b-PNIPAM block copolymers display hydrophilic properties at room temperature and amphiphilic properties in the range from 35 degrees C to 80 degrees C. Surface tension measurements at different concentrations confirmed the low critical micelle concentration (CMC) of the PEG-PNIPAM block copolymers, with a minimum value as low as 9.10x10(-3) g/L. Evaluations of particle size distribution and emulsification performance validated its applicability as an emulsifier in emulsion polymerization within the aforementioned temperature range. Microscopic observations of latex particles corroborated the precise occurrence of emulsion polymerization, displaying a relatively uniform particle size distribution in the resulting polymer. Upon completion of the emulsion polymerization reaction, the need for additional agents such as demulsifiers or physical methods like mechanical stirring was obviated. Merely lowering the reaction system to room temperature facilitated demulsification, yielding the desired polymer products. Further, rapid demulsification could be achieved by cooling the reaction system at lower temperatures (3.8 degrees C). Utilizing PEG-b-PNIPAM block copolymers as surfactants allowed the temperature-controlled emulsification and demulsification processes, significantly streamlining the emulsion polymerization process, reducing costs, and enabling environmentally friendly production practices.

Abstract ：
Copper metal is essential to our production process, but it is highly corrosive in an ammonia environment and must be highly valued. Anti-corrosion coating is a simple and cost-effective method of preventing metal corrosion. In this study, a composite silane coating was prepared on copper using an impregnation method with mercaptopropyltriethoxysilane (TPTES) as the silane substrate and graphene oxide (GO) modified with isophorone diisocyanate (IPDI) or isocyanatopropyltriethoxysilane (IPTS) as filler to protect the copper from ammonia corrosion. The coating samples were hanging tested against ammonia corrosion by setting up two corrosive environments: ammonia gas and ammonia water. After 20 days of corrosion, the surfaces of the TPTES/ IPDI-GO and TPTES/IPTS-GO coatings remained unchanged under both ammonia environments and the corrosion rate was consistently low at 2-3 mu m/y. Additionally, the coating exhibited high protective qualities according to the electrochemical impedance spectroscopy (EIS) test in a 3.5% NaCl solution, which is attributed to the good dispersion that improves the densification and regularity of the coating. Meanwhile, IPTS-GO has a greater binding force with the coating matrix due to the increased number of reactive sites, resulting in further improved corrosion protection. This study provides an idea for research on ammonia-resistant coatings.
