Abstract
Materials and Methods are provided for fabricating microfluidic devices. The materials include low surface energy fluoropolymer compositions having multiple cure functional groups. The materials can include multiple photocurable and/or thermal-curable functional groups such that laminate devices can be fabricated. The materials also substantially do not swell in the presence of hydrocarbon solvents.

A polymer composition, comprising:
- a first component including a fluoropolymer having a first curable functional group, wherein the fluoropolymer having a first curable functional group comprises a diurethane methacrylate functionalized perfluoropolyether having one of the following structures:
- wherein n′ is an integer from 1 to 100, and n is one;
- and a second component including a polymer having a second curable functional group, wherein the polymer having said second curable functional group is a fluoropolymer, wherein said fluoropolymer comprises:
- (a) a diisocyanate functionalized perfluoropolyether having a structure of:
- wherein n′ is an integer from 1 to 100;
- (b) a diisocyanate functionalized perfluoropolyether having a structure of:
- wherein n′ is an integer from 1 to 100;
- (c) a diepoxy functionalized perfluoropolyether having a structure of:
- wherein n′ is an integer from 1 to 100;
- or
- (d) a diamine functionalized perfluoropolyether having a structure of:
- wherein n′ is an integer from 1 to 100.
