Abstract:

This report describes the technical accomplishments obtained for the project entitled Synthesis and Characterization of Block Copolymers with Unique Chemical Functionalities and Entropically-Hindering Moieties. Novel ionic block block copolymersionomers with multiple ionic domains were synthesized using atom transfer radical polymerization ATRP. The resulting ionomer membranes were extensively characterized to understand the chemical EA, FT-IR, NMR, thermal TGA, DSC, morphological AFM, SAXS, SANS, and transport properties for direct methanol fuel cell applications e.g., proton conductivity and methanol permeability. Unique synergistic effects were observed due to the different ionic domains e.g., sulfonic, ether, ketone, etc..
