    Fabrication of Polyaniline Nanoparticles via the co-Assembly of Macromolecules

    • 摘要: 首先,以丙烯酸(AA)、N-乙烯基吡咯烷酮(VP)和苯乙烯(St)为聚合单体,通过自由基共聚法合成了一种双亲无规共聚物P(AA-co-VP-co-St)。 然后,在疏水作用和静电作用的共同诱导下,将该共聚物与聚苯胺(PANI)共组装形成形态可控且均匀分散的PANI纳米粒子。通过透射电子显微镜和激光动态光散射等研究了P(AA-co-VP-co-St)和 PANI在水溶液中的共组装行为,并系统研究了亲水单体AA的物质的量分数对所制备的PANI纳米粒子粒径、形态的影响。结果表明:当AA物质的量分数为30%时,PANI纳米粒子的粒径最小。

       

      Abstract: The amphiphlic random copolymer P(AA-co-VP-co-St) was synthesized by free radical polymerization of acrylic acid (AA),N-vinyl pyrrolidone (VP) and styrene (St).Driven by the hydrophobic effect and the electrostatic interaction,P(AA-co-VP-co-St) and PANI could be co-assembled into uniformly dispersed PANI nanoparticles.The co-assembly behaviors between P(AA-co-VP-co-St) and PANI in aqueous solution were studied using transmission electron microscopy and dynamic light scattering.The influences of AA mole fraction on the size and morphology of the obtained PANI nanoparticles were systematically studied.Results showed that the minimum size of PANI nanoparticles was obtained at AA mole fraction of 30%.
