Abstract

Poly(3,4-ethylenedioxythiophene) (PEDOT) is a conductive polymer used in batteries, supercapacitors, solar cells, and various biosensors in wearable electronics. Through controlled atom transfer radical polymerisation (ATRP), it is possible to modify the properties of PEDOT for specific applications by grafting the side branches. In this work, PEDOT-based ATRP macroinitiators, functionalised with reactive bromine allowing the grafting of different polymers as side branches, were synthesised. Characterisation of the obtained samples was carried out by NMR, FTIR, GPC, TGA and measurement of electrochemical properties. Results showed that the sample with lower bromine content had better chemical properties; hence it was more suitable for further synthesis and modification of PEDOT.
