Nanoporous media templated from unsymmetrical amphiphilic porogens
First Claim
1. A substantially spherical micellar structure formed by one or more spatially unsymmetric organic amphiphilic molecules, each comprising:
- (a) a branched moiety that forms part of either the core or the surface of the substantially spherical micellar structure, and(b) a second moiety that forms part of either(b1) the surface of the substantially spherical micellar structure when the branched moiety forms part of the core, or(b2) the core of the substantially spherical micellar structure when the branched moiety forms part of the surface,wherein the second moiety is a linear polymeric moiety having a degree of polymerization of between 50 and 500, andwherein the substantially spherical micellar structure exists in a thermosetting polymeric matrix.

Abstract
Substantially or roughly spherical micellar structures useful in the formation of nanoporous materials by templating are disclosed. A roughly spherical micellar structure is formed by organization of one or more spatially unsymmetric organic amphiphilic molecules. Each of those molecules comprises a branched moiety and a second moiety. The branched moiety can form part of either the core or the surface of the spherical micellar structure, depending on the polarity of the environment. The roughly spherical micellar structures form in a thermosetting polymer matrix. They are employed in a templating process whereby the amphiphilic molecules are dispersed in the polymer matrix, the matrix is cured, and the porogens are then removed, leaving nanoscale pores.
