Ionic membrane preparation

摘要

In a first aspect, a method for forming a ionic polymer membrane, comprises: (i) polymerising a mixture of one or more first monomers to form an ionic polymer membrane; (ii) soaking the polymer membrane of (i) into a mixture of one or more second monomers, for a sufficient length of time to allow the solution to penetrate through the entire polymer membrane; and (iii) polymerising the monomer-coated polymer of step (ii) to form an essentially homogenous ionic polymer. In a second aspect, a method for forming a catalyst-coated ionic polymer membrane, comprises: (i) polymerising a mixture of one or more first monomers to form an ionic polymer membrane; (ii) dipping the polymer of (i) into a mixture of one or more second monomers; (iia) depositing a catalyst onto the monomer-coated polymer; (iii) polymerising the monomer-coated polymer of step (iia). The present invention also includes membranes formed using these methods.

1. A method for forming an ionic polymer membrane, comprising:
step (i) polymerising a mixture of first monomers to form an ionic polymer membrane; step (ii) soaking the polymer membrane formed in step (i) in a mixture of second monomers, for a sufficient length of time to allow the mixture of second monomers to penetrate through the entire polymer membrane and form a monomer-penetrated polymer, wherein at least one of the mixture of first monomers and the mixture of second monomers comprises an ionic component; and step (iii) polymerising the monomers of the monomer-penetrated polymer of step (ii) to form an essentially homogenous ionic polymer, wherein a catalyst is deposited onto the monomer-coated polymer in between steps (ii) and (iii).
