Abstract
Official abstract text for this publication.
Provided is a composite which is comprised of one or more ion exchange resin(s) and a porous fluorine containing polymer membrane ( 2 ), wherein the porous membrane and the resin form a carbon-chain crosslinked structure, so that the film prepared from the composite is of good airtightness and stability, as well as high ion exchange capacity and high conductivity. The preparation method of the composite, the product prepared from this composite and the application thereof are also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite material, wherein (a) said composite material is formed by filling micropores and covering surfaces of a porous fluoropolymer membrane with one or more ion exchange resins, the one or more ion exchange resins having an ion exchange function and comprising acidic exchange groups; (b) the pore surfaces of said porous fluoropolymer membrane are modified by bromine-containing functional monomers through grafting; and (c) a carbon-chain cros…
