摘要:	研究期間：10108~10207;Polymer morphology has an impact upon both the proximity of acid groups and degree of tortuosity of the hydrophilic network. The morphology adopted by the ionomer is dictated by the number and placement of the acid groups within the membrane, which in turn is governed by the chemical structure/ composition of the polymer. For block copolymer, more work are required to gain insight and control over self-assembled structures, and to fully grasps the interplay of ordering and alignment upon critical PEM parameters such as water transport, fuel permeation, proton conduction and membrane stability. Present proposal explores new types of proton exchange membrane bearing long range ordered nano-structures created by self-assembly of block copolymers where water/fuel transport is motivated, and proton transfer enhanced due to the Electrostatic interactions established among the ordered domains. Four major tasks are proposed to carry-out in the next two to three years: I. Preparation of block copolymers self-assembly membranes bearing long range ordered nano-domain phase: di-and tri-block copolymer membranes with various structure characteristics (acid group distribution, spacer motion) and ordered morphology are prepared. II. Self assembly membranes by Protein-Based Block Copolymers: Self-assembly of three-dimensional solid-state nanostructures containing globular protein using a globular protein_polymer diblock copolymer, provided for use in bioelectronic and biocatalytic materials for Microbial fuel cell, and for proton conduction in PEM fuel cell. III.Organic-inorganic net-work composite membranes: Three designs with nano-structures are explored: (1) Organic-inorgainc composites with long range ordered inorganic nano domain, (2) Membrane bearing Electric field poled TiO2 nanotube and (3) Proton conducting membranes with highly dispersed Hyperbranched and Dendrimer based nano-domains. IV.Proton conducting mechanisms in Nano-phase ordered membrane: The purpose of the study is to understand chemical and structure factors governing proton conduction in ordered nano-structures, and to unveil new driving force in these structures under high temperature and low-humidity conditions. More appropriate morphology for water/fuel and proton conduction can be unveiled and new proton conducting mechanism discovered from nano-phase separated domains with this design.
