Abstract ：
Triboelectric nanogenerators (TENGs), as a new strategy for harvesting energy from nature, have attracted widespread attention in the field of water droplet energy capture. As a friction layer material, the solid[sbnd]liquid electrification phenomenon of coatings has been studied. However, little attention is paid to the influence of the surface wettability of the coating itself on the electrical signal of the droplet generator. In this study, alkyl/phenyl pure silicone resin was utilized as a substitute for fluorine-containing polymer materials. This substitution not only mitigated the risk of environmental pollution from TENG friction materials but also resulted in varying wettability of the silicone resin coating through plasma and surface structure treatment. The droplet-based Double-electrode (D-TENG) and Single-electrode (S-TENG) coating-based triboelectric nanogenerators were fabricated. Through the integration of a high-speed camera and ammeter, the motion state of water droplets on surfaces with different wettability closely correlates with their charged behavior. This correlation is utilized to observe the motion state of water droplets on hydrophilic-hydrophobic surfaces in four stages: contact, spreading, contraction, and sliding. Under the double-electrode structure, as the water contact angle of the coating increased from 6.84° to 139.77°, the short-circuit current initially increased and then decreased, peaking at 466 µA when the contact angle was 98.48°, representing a 677-fold increase from the initial 0.689 µA. In the single electrode structure, the short-circuit current increased from 2.66 nA to 700 nA, indicating a 263-fold increase. Studying the varied wettability of the surface of silicone resin coating aids in comprehending the application of the coating material in solid-liquid friction electrification for energy collection. Furthermore, it offers insight into selecting appropriate coating materials for friction coatings in future applications. © 2024 Elsevier Ltd

Abstract ：
Cement concrete pavement is prone to early deterioration during the construction phase, and the early performance during the construction phase is significantly affected by the external temperature and humidity field. This article selects meteorological parameters in the Fuzhou area as a typical representative of a humid and hot climate and develops a three-dimensional humidity simulation program based on Fick's law and the finite difference method to study the evolution behavior of the humidity field in early age of cement concrete pavement. It discusses the humidity distribution characteristics of road panels and analyzes the influence and sensitivity of cement type, construction conditions, and road panel structural parameters on road panel humidity. Research has shown that the evolution law of the humidity field of road panels shows a 24-h periodic change with the external environment. The environmental field has a significant impact on the surface humidity of road panels. The horizontal humidity of the panel is concentrated from the boundary to the middle of the panel, and the tangential humidity is concentrated from the top to the bottom of the panel. The humidity field of road panels is the most sensitive to environmental humidity and maintenance methods, but less sensitive to material and structural parameters. Therefore, during construction, it is possible to avoid the hot season and choose a time period when the environmental humidity increases to pour concrete. Appropriate maintenance methods are adopted to reduce the humidity stress of the panels, reduce early age deterioration, and improve their service life.

Abstract ：
Airport pavements are prone to early defects during the construction phase, and their early performance during the construction phase is significantly affected by the external temperature field. This article takes the concrete pavement of Xiamen Xiang'an New Airport as an example and uses a three-dimensional (3D) humidity simulation program for cement concrete pavement to study the evolution behavior of the early stage humidity field of the pavement in a humid and hot climate environment. The results indicate that the evolution law of the humidity field of the concrete pavement slab was consistent with the environmental field, presenting a 24 h periodic variation. The environmental field had a significant impact on the humidity of the surface layer of the pavement slab, and the humidity decreased rapidly with time. There was a humidity gradient on both the horizontal plane and the cutting plane of the slab, the horizontal humidity was concentrated from the boundary into the middle of the slab, and the sectional humidity was concentrated from the top to the bottom of the slab. Environmental parameters, construction parameters, and material and structural parameters all influenced humidity through humidity exchange or by changing the saturated vapor pressure inside the slab. The humidity field was most sensitive to environmental humidity and maintenance methods, but less sensitive to material parameters and structural parameters. Through analysis, it is advisable to avoid hot seasons, choose periods of increased environmental humidity, adopt appropriate maintenance methods during construction to reduce humidity stress on the slab, and therefore decrease early stage deterioration and improve service life.

Abstract ：
Based on a creep model for microprestress-solidification theory, considering the influence of material, structure and environmental parameters, a three-dimensional simulation program for early-age mechanical behavior of pavement was established, and the creep effects mechanism of three-dimensional pavement structure were analyzed. The results show that creep is a relaxation effect on early-age pavement, which significantly reduces the early-age curling and stress. The influence magnitude of creep on early-age behavior of pavement is similar to that of temperature gradient and that of edge constraint. Creep effect is also significantly affected by edge constraint, temperature gradient, humidity gradient and overall temperature conditions, and has spatial position non-uniform distribution characteristics. Under the effect of creep, the maximum relaxation position of stress is close to the middle of the restricted edge. The creep relaxation effect has significant time-dependent characteristics. It is most significant in the first 7 days and tends to be stable after 60 days. Creep relaxation effect increases significantly with temperature gradient and overall temperature increasing. Theoretical comparison shows that, ignoring the influence of temperature will underestimate the creep effect under high temperature and overestimate the creep effect under low temperature. It is recommended to use creep effect design to reduce early-age curling and stress in pavement engineering. Copyright ©2022 Engineering Mechanics. All rights reserved.

基于水泥混凝土路面板早龄期力学仿真,开展夏季不同施工时段、边界约束对面板固化性状的影响研究.结果显示,施工季节、昼夜温差、结构约束等显著影响固化翘曲和残余应力.面板早龄期存在典型的板角向上固化翘曲和不对称翘曲模式,面板28 d残余应力主要为板顶受拉形式.接缝约束显著减小约束边板角翘曲,增大面板板顶残余拉应力分布面积,应力峰值影响较小.研究提出零平均应力温度梯度参数表征固化翘曲和初始应力状态两方面影响,面板早龄期温度加载历史中正温度差量级、时长较大,面板早期更易形成零平均应力正温度梯度.计算早龄期性状影响效应时,28 d零平均应力温度梯度范围可考虑取值0.25～0.57℃·cm-1区间.

Abstract ：
为了解路面板早龄期应力性状与行为特征,基于福建夏季高温、冬季低温、隧道恒温进行了3种典型环境条件的路面板早龄期行为现场试验.采用无应力圆筒装置去除路面板温湿度无应力应变,基于应变历史结合步进法考虑徐变松弛获得路面板典型监测位置应力性状和时程.同步监测路面板早龄期温度场和整板翘曲,比较路面板早龄期应力与温度梯度、翘曲变形的相互关系.研究显示,路面板早龄期应力一般存在压应力、拉应力、应力波动循环3个阶段,应力波动循环初期存在一个松弛阶段.路面早龄期应力主动影响因素有水化放热、环境场温湿度变化、翘曲变形和重力的联合作用,初期水化热升降温效应显著,后期温度翘曲效应显著.被动影响因素有水泥混凝土早龄期行为、结构约束、边界条件等.夏季施工面板早龄期应力和翘曲量级显著高于冬季,隧道恒温条件下面板由于湿度收缩会形成板角始终向上的凹形固化翘曲.早龄期应力波动和松弛过程的存在,造成路面板初期运营的一段时间的应力与后期正常服役期并不相同,需要规避可能与设计状态不符的初期不利工况.
