Abstract

Polythiophene (PT) was grafted on PE film using three reaction steps. First, PE films were brominated in the gas phase, yielding PE-Br; second, a substitution reaction of PE-Br with 2-thiophene thiolate anion gave the thiophene-functionalized PE; finally PT was grafted on the PE surface using chemical oxidative polymerization to give PE-PT. The polymerization was carried out in a suspension solution of anhydrous FeCl₃ in CHCl₃, yielding a reddish PE-PT film after dedoping with ethanol. ATR-FTIR shows that the PT was grafted on PE in the 2,5-position. SEM imaging revealed islands of PT on the PE film. AFM analysis found the thickness of islands to be in the range of 120-145 nm. The conductivity of these thin films was in the range of 10^-6 S cm^-1, a significant increase from the value of ∼10^-14 S cm^-1 measured for PE film.
