The goal of this study is to synthesize, characterize and investigate some physicochemical properties of conductive polyaniline-g-polystyrene/FeO (FeO/PSt-g-PANi) nanocomposites. For this purpose, initially, FeO nanoparticles were synthesized by a co-precipitation method. Then, the desired nanocomposite was synthesized in two steps. First, the atom transfer radical polymerization (ATRP) of styrene was performed using an ATRP initiator attached to the surface of FeO nanoparticles, followed by functionalization of the FeO-PSt with amine groups (-NH). Second, surface oxidative graft copolymerization of aniline was accomplished using the -NH moieties on the FeO/PSt-NH as the anchoring sites. The prepared materials were characterized by various instruments, including TEM, SEM, TGA, EDX, FT-IR, XRD and conductivity measurements. The results indicated that the synthesized conductive polymer/FeO nanocomposites had higher electrical conductivity and thermal resistance than those of the corresponding homopolymers.
本研究的目的是合成、表征和研究一些导电聚苯胺-聚苯乙烯/FeO(FeO/PSt-g-PANi)纳米复合材料的物理化学性质。为此,首先通过共沉淀法合成了 FeO 纳米粒子。然后,通过两步法合成所需的纳米复合材料。首先,使用附着在 FeO 纳米粒子表面的 ATRP 引发剂进行苯乙烯的原子转移自由基聚合(ATRP),然后用胺基(-NH)官能化 FeO-PSt。其次,通过 FeO/PSt-NH 上的-NH 部分作为锚固位点,完成苯胺的表面氧化接枝共聚。通过各种仪器对制备的材料进行了表征,包括 TEM、SEM、TGA、EDX、FT-IR、XRD 和电导率测量。结果表明,与相应的均聚物相比,合成的导电聚合物/FeO 纳米复合材料具有更高的电导率和耐热性。
