Title STRUCTURED NANOPOROUS MATERIALS, MANUFACTURE OF STRUCTURED NANOPOROUS MATERIALS AND APPLICATIONS OF STRUCTURED NANOPOROUS MATERIALS
Abstract A method is disclosed for manufacturing a structured polymeric material. In the method, a body is provided comprising a substantially homogenous precursor polymeric material. An interference pattern of electromagnetic radiation is set up within the body to form a partially cross-linked polymeric material, the interference pattern comprising maxima and minima of intensity of the electromagnetic radiation, the interference pattern thereby causing spatially differential cross linking of the precursor polymeric material to form crosslinked regions having relatively high cross linking density and non-crosslinked regions having relatively low cross linking density, the crosslinked regions and non-crosslinked regions corresponding to the maxima and minima of intensity of the electromagnetic radiation, respectively. The partially cross-linked polymeric material is then contacted with a solvent to cause expansion and crazing of at least some of the non-crosslinked regions to form a structured polymeric material containing pores.
Outline of related art and contending technology BACKGROUND TO THE INVENTION
Field of the invention
The present invention relates to structured nanoporous materials, methods for the manufacture of structured nanoporous materials and applications of structured nanoporous materials. Such materials have utility in various technical fields, particularly, but not exclusively, in optical technology such as for anti-counterfeiting measures, and in microfluidic technology such as for diagnostic applications.
