Abstract
Template-based methods fabricate organosilicate materials with mesoscopic structures. The methods include providing solutions of amphiphilic template molecules, mixing amphiphilic organosilicate precursors into the solutions to form mixtures, and evaporating solvent from the mixtures. The evaporation steps produce composites in which the amphiphilic organosilicate precursors have nontrivial mesoscopic structures.
Claims13
A method, comprising:
- providing a solution of amphiphilic template molecules;
- mixing amphiphilic organosilicate precursors into the solution to form a mixture;
- and
- evaporating solvent from the mixture to produce an organosilicate composite with a mesoscopic structure;
- curing the composite in a manner that crosslinks at least a portion of the organosilicate precursors;
- and wherein the amphiphilic organosilicate precursors remain amphiphilic during curing.

A method comprising:
- forming a composite with an internal structure by evaporating solvent from a solution comprising amphiphilic block copolymer molecules and amphiphilic organosilicate precursors;
- and
- crosslinking a portion of the organosilicate precursors of the composite to form an organosilicate solid;
- and
- wherein the crosslinking conserves an amphiphilic nature of at least a portion of the organosilicate precursors incorporated into the solid.
