Abstract
A process is described for preparing structured organic-inorganic hybrid materials, using an amphiphilic block copolymer as template.
Claims40
A process for preparing structured organic-inorganic hybrid materials, comprising the steps:
- (a) forming a mixture comprising at least one mesophase of an amphiphilic organic block copolymer consisting essentially of at least one hydrophilic block and at
- least one hydrophobic block as template and comprising at least one precursor which can be reacted to give an inorganic solid,
- (b) reacting the precursor in a bulk phase or in a mesophase that is free from solvent, and
- (c) optionally removing any volatile constituents from the reaction mixture, to produce the organic-inorganic hybrid material,
- wherein a hydrophobic block in the amphiphilic block copolymer has a glass transition temperature of Tg≦50° C.

A process for preparing structured organic-inorganic hybrid materials, comprising the steps:
- (a) preparing a sol comprising a precursor which can be reacted to give an inorganic solid,
- (b) adding the sol from (a) to a mesophase of an amphiphilic organic block copolymer consisting essentially of at least one hydrophilic block and at least one hydrophobic block as template,
- (c) reacting the precursor in a bulk phase or in a mesophase that is free from solvent to form a gel, and
- (d) optionally removing any volatile constituents from the reaction mixture, to produce the organic-inorganic hybrid material.
