Abstract

A novel basic proton conducting polymer (so-called proton-vacancy conducting polymer) has been synthesized. It is based on the copolymerization via the sol-gel process of sulfonamide- containing groups, partially deprotonated, and an internal plasticizer (POE segments). All the organic groups are attached to trialkoxysilanes which, through the hydrolysis-condensation process, lead to a silica-based backbone. The flexible films obtained are homogeneous and transparent. Maximum conductivities are observed with approximately equals 15% of the sulfonamide groups deprotonated by the organic base and approximately equals 10% of 2000 M_w POE plasticizer. The conductivity values are 2 10^-7Ω^-1-cm^-1 at 30 degree(s)C and 10^-5 Ω ^-1cm^-1 at about 84 degree(s)C. The polymers are thermically stable up to 220 degree(s)C and their electrochemical stability range is close to 2 V.
