Film

Abstract

The present invention provides a film for attaching a nanostructured material to a surface of a substrate, comprising: (a) a removable support; (b) an attaching layer for attaching the film to the surface of a substrate; and (c) the material directly coupled to the support and the attaching layer. Methods for making the film, methods for attaching the material to the surface of a substrate are also provided. The present invention further provides a surface having a material attached thereto by means of the attaching layer. Using the methods disclosed herein, a material having a high specific surface area (SSA) and having particular proper ties (e.g. super-hydrophobicity) can be applied to a substrate including a fuel cell, a conductive electrode, a dye sensitized solar cell, a diffuse reflective mirror, eyewear, a window and a vehicle (e.g. car) windscreen, for example to provide a self-cleaning surface.
