Abstract
A rapid and inexpensive technique for generating nanotextured surfaces is disclosed. The technique involves the (1) creation of regular, nanometer-sized template by microwave assisted hydro- or solvo-thermal treatment of polymer films coated on surfaces followed by (2) coating of a layer of metal, metal oxides, polymers and inorganic materials. The nanometer-sized polymer template could be removed to create regularly shaped, hollow nanostructures (e.g., nano-bottles, nano-bowls, nano-holes etc.).
Claims20
A method for creating a nanotextured surface, comprising (a) depositing a polymer film on a substrate;
- and (b) transforming the polymer film into uniform islands of a regularly shaped, nanometer sized template solely by a microwave-assisted hydro- or solvo-thermal treatment.
