Synthesis and adsorption properties of special micro-morphological polypyrrole

Polypyrrole (PPy) is a kind of conductive polymer material with excellent performance. Recent research focuses on the application of PPy and its composite materials in electrochemistry, but the studies of the special micromorphology and adsorption performance of PPy composites are rarely concerned. This paper summarizes the synthesis method of special micro-morphological PPy and its composites such as PPy/metal element, PPy/metal oxide, PPy/dyes and PPy/non-metal elements, and further analyzed the differences in the morphology of PPy and its composites. It was concluded that difference in micromorphology can affect the material properties. We briefly introduced current report on the application of PPy composites in the field of adsorption, and put forward the effects of different micro-morphologies on the adsorption properties. We also analyzed the excellent adsorption performance of PPy composites on dyes and heavy metals. This paper points out the great application prospect and commercial value of PPy and its composites with special micromorphology in the field of adsorption.
