导电性微纳米结构N-乙基苯胺/苯胺共聚物的静态合成

以N-乙基苯胺（NA）、苯胺（AN）为单体,过硫酸铵（APS）为引发剂,通过静态聚合法制备了导电性微纳米结构N-乙基苯胺-苯胺共聚物（PNAAN）。结果表明,共聚物的形貌、结构和性能强烈依赖于NA/AN物质的量比和APS/单体物质的量比。APS/单体物质的量比为1.0时,PNAAN（10∶90）共聚物为直径139 nm...

Unstirred Polymerization of Conductive Micro/Nano-Structural Copolymers from N-Ethylaniline with Aniline

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 nm~186 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 μm~3.6 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.
