Polyethylene glycol – Polyaniline diblock and triblock copolymers: Synthesis and characterization

Polyaniline (PANI), one of the most important conducting polymers has attracted considerable attention owing to its facile synthesis, controllable electrical conductivity andinteresting redox properties [1] and its application in neuronal devices, chemical sensors and artificial muscles, etc [2].Forimprove the chemical and physical properties, various modifications were be done. Copolymerization, blending, grafting of several groups on polymer backbone. Forimprovement of the solubility and processability of polyaniline, preparation of diblock and triblock of polyaniline and polyethylene glycol (PEG 2000, 6000, 20000) wasconsidered here. Novel copolymers containing electroactive polyaniline and polyethylene glycol were synthesized formedical application. 1HNMR was used to characterize the chemical structure. The electrochemical properties and thermal behaviour of the polymer were investigated by cyclic voltammetry (CV) and differential scanning calorimetry (DSC).
