摘要：
A novel rod-coil diblock copolymer, tetraaniline-b-PEEG in short, was prepared from electroactive tetraaniline and hydrophilic poly (ethylene glycol) and characterized using infrared and UV-vis spectra. Gel permeation chromatography (GPC) was used to measure its molecular weight and molecular weight distribution, and a narrow molecular weight distribution of 1.29 stated that the resulting tetraaniline-b-PEG copolymer possessed uniform and nearly monodispersed block structures. The electroactivity of tetraaniline-b-PEG in hydrochloric acid aqueous solution was confirmed using cyclic voltammetry, and one pair of redox peaks was detected which could be attributed to the transition between LB and ES state of tetraaniline block in copolymer.
