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.
Claims17
A method for pattern transfer of a micro-scale or nano-scale pattern, comprising:
- contacting a fluoropolymer with a master template, wherein the master template includes a dimensional pattern;
- curing the fluoropolymer such that the cured fluoropolymer has a dimensional pattern that substantially corresponds to the dimensional pattern of the master template;
- removing the cured fluoropolymer from the master template;
- contacting a silicone with the dimensional pattern of the cured fluoropolymer;
- curing the silicone such that the cured silicone is a substantial replicate of the dimensional pattern of the master template;
- and
- removing the cured silicone from the fluoropolymer.

A method for making a mold, comprising:
- contacting a silicone with a polymer layer defining a dimensional pattern;
- curing the silicone while in contact with the dimensional pattern of the polymer layer to form a silicone layer that has a dimensional pattern that substantially corresponds to the dimensional pattern of the polymer;
- and,
- removing the silicone layer from the polymer layer.
