Unstirred Polymerization of Conductive Micro/Nano-Structural Copolymers from N-Ethylaniline with Aniline
Translated Abstract
Conductive micro/nano-structural poly（N-ethylaniline-co-aniline）（PNAAN） copolymers were synthesized via unstirred polymerization of N-ethylaniline（NA） and aniline（AN） with ammonium peroxydisulfate as an oxidant.Morphology,structure and electrical conductivity of the copolymers were characterized by means of SEM,TEM,FT-IR,UV-vis,and four-probe techniques.It is found that the structure,morphology and properties of the copolymer strongly depend on the NA/AN molar ratio.PNAAN（10/90） copolymer nanofibers in diameters of 139 nm186 nm and lengths up to 4.2 μm were prepared with APS/comonomer molar ratio of 1.0,whereas PNAAN（50/50） copolymer spheres with smooth surface（1.3 μm3.6 μm in outer diameter） were produced during the same above-mentioned polymerization conditions.While the PNAAN（90/10） copolymer self-assembled hollow microspheres with coarse surface（4.45 μm in outer diameter） were obtained.The SEM image reveals that the PNAAN（50/50） copolymer spheres are constructed with their own nanofibers by self-assembly process.The as-synthesized PNAAN copolymers possess good room-temperature electroconductivity and solubility.
