Synthesis and characterization of eco-friendly composite: Poly(Ethylene Glycol)-grafted expanded graphite/polyaniline

Abstract

In this paper, synthesis and characterization of poly(ethylene glycol)- grafted expanded graphite/polyaniline (PEG-grafted EG/PANi) as a novel ecofriendly composite material was reported. EG as substrate prepared from expandable graphite was firstly synthesized by in-situ polymerization at the presence of aniline (An) to obtain EG/PANi, and then graft polymerization with as-prepared PEG-grafted PANi (PEG-g-PANi) composite under no tough conditions. Structural characteristics of the products were evaluated by infrared spectrum (IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. The experimental results have shown that the product of PEGgrafted EG/PANi composite were synthesized by facile method. © 2011 Springer-Verlag Berlin Heidelberg.
