Title:
NANOPOROUS MATERIALS, MANUFACTURE OF NANOPOROUS MATERIALS AND APPLICATIONS OF NANOPOROUS MATERIALS
Document Type and Number:
WIPO Patent Application WO/2012/035292
Kind Code:
A3
Abstract:
A nanoporous material is disclosed having a plurality of lamellae. Through each lamella is an array of penetrating pores. Adjacent lamellae are spaced apart by an intervening spacing layer. The spacing layer comprises an array of spacing elements integrally formed with and extending between the adjacent lamellae. The spacing layer has interconnected porosity extending within the spacing layer. Such a nanoporous material can be manufactured using block copolymer materials. First, a morphology is formed comprising a three dimensional array of isolated islands in a continuous matrix. The islands are formed of at least one island component of the block copolymer and the matrix is formed of at least one matrix component of the block copolymer. Next, channels are formed in the matrix between at least some of the islands. The island component is then selectively removed to leave the matrix with an array of interconnected pores.
