Abstract
Organosilicate materials and methods for preparing organosilicate materials, including organosilicate films are provided. The organosilicate materials are hydrophobic, amorphous, and substantially microporous. These materials are prepared from organo-functional hydrolysable silane precursors and are prepared without the use of porogens. These materials are suitable for a wide range of uses, including as detection layers for sensing applications.
Claims19
A film comprising:
- a hydrophobic, amorphous, substantially microporous, organosilicate composition comprising micropores which define a pore volume, and wherein the organo-functional silicate composition comprises a composition prepared from a precursor reaction mixture comprising:
- a solvent;
- at least two organo-functional hydrolysable silanes;
- and
- an acid.

A method for preparing a film comprising:
- providing a substrate;
- providing a precursor reaction mixture comprising:
- a solvent;
- at least two organo-functional hydrolysable silanes;
- and
- an acid;
- coating the precursor mixture on the substrate;
- and
- heating the coated mixture to a temperature sufficient to form a calcined film, wherein the film comprises:
- a hydrophobic, amorphous, substantially microporous, organosilicate composition comprising micropores which define a pore volume.
