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.
Claims20
A method for pattern transfer of micro-scale and nano-scale cavities, comprising:
- contacting a fluoropolymer with a master template, wherein the master template includes a dimensional pattern;
- curing the fluoropolymer such that the fluoropolymer retains a substantial replicate of the dimensional pattern;
- removing the cured fluoropolymer from the master template;
- contacting a poly(dimethylsiloxane) with the dimensional pattern of the cured fluoropolymer;
- curing the poly(dimethylsiloxane);
- and
- removing the cured poly(dimethylsiloxane) from the cured fluoropolymer wherein the dimensional pattern of the cured poly(dimethylsiloxane) is a substantial replicate of the dimensional pattern of the master template.
