Abstract
A laminate nanomold includes a layer of perfluoropolyether defining a cavity that has a predetermined shape and a support layer coupled with the layer of perfluoropolyether. The laminate can also include a tie-layer coupling the layer of perfluoropolyether with the support layer. The tie-layer can also include a photocurable component and a thermal curable component. The cavity can have a broadest dimension of less than 500 nanometers.
Claims43
A laminate nanomold system comprising:
- a layer of perfluoropolyether, wherein the layer of perfluoropolyether includes a first surface defining a plurality of cavities, wherein each cavity of the plurality of cavities has a predetermined shape and is less than about 10 micrometers in a largest dimension, and wherein the layer of perfluoropolyether is less than about 75 micrometers in thickness;
- a support layer bonded to a second surface of the layer of perfluoropolyether opposite the first surface, wherein the support layer bonded to the layer of perfluoropolyether has a combined modulus greater than about 1400 MPa;
- a sheet positioned to face the first surface of the layer of perfluoropolyether;
- a material disposed between the sheet and the first surface of the layer of perfluoropolyether, the material configured to conform to the cavities of the first surface;
- and
- a first roller and a second roller defining a nip point configured and dimensioned to receive the layer of perfluoropolyether bonded to the support layer, the sheet, and the material.
