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.
Claims20
A method of making a laminate mold comprising:
- positioning a patterned master comprising a pattern defining structures adjacent to a support layer;
- positioning the patterned master and adjacent support layer adjacent a nip;
- positioning a polymer material between the patterned master and the support layer adjacent an input side of the nip;
- passing the patterned master, polymer material and support layer together through the nip to form a laminate from the patterned master with the support layer, wherein the polymer material is dispersed between the patterned master and the support layer in the laminate;
- conforming the polymer material in the laminate such that the polymer material conforms to the structures defined in the patterned master to create a mold layer from the polymer material, wherein the mold layer comprises a pattern of structures that substantially mirrors the pattern of the patterned master;
- and
- removing the patterned master from the mold layer, wherein the mold layer is coupled with the support layer and the coupled support layer with mold layer has a combined modulus at least 200 times the modulus of the mold layer alone.

A method of making a laminate mold comprising:
- nip rolling a patterned master comprising a pattern defining structures with a polymer material against a support layer;
- forming a laminate from the polymer material and the support layer;
- and
- conforming the polymer material in the laminate such that the polymer material conforms to the structures defined in the patterned master to create a mold layer from the polymer material, wherein the mold layer comprises a pattern of structures that substantially mirrors the pattern of the patterned master,
- wherein the mold layer coupled with the support layer has a combined modulus at least 200 times the modulus of the mold layer alone.
