Abstract
Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.
Claims16
A method for solution casting a nanostructure, the method comprising:
- preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining;
- replicating the nanoholes by applying a solution of a polymer and a solvent into the template;
- and
- after the solvent has substantially dissipated, removing the replica from the substrate.
A method for casting a nanostructure, the method comprising:
- preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining;
- replicating the nanoholes by applying a polymer resin into the template;
- and
- after the resin has set, removing the replica from the substrate
A method for solution casting a nanostructure, the method comprising:
- preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining;
- replicating the nanoholes by casting a solution of a polyethylene and a solvent into the template;
- after the solvent has substantially dissipated, melting the polyethylene as cast in the template;
- cooling the melted polyethylene as cast in the template to room temperature;
- and
- removing the cooled polyethylene replica from the substrate.
