Abstract
The present invention provides a monolithic silicone in the form of an aerogel or a xerogel having flexibility and capable of dissolving molecules of a substance. This silicone monolithic body having continuous through passages is synthesized by copolymerizing starting materials of both a bifunctional alkoxysilane and a trifunctional alkoxysilane or tri- or higher functional alkoxysilanes through a sol-gel reaction for forming a Si—O network while causing phase separation.
Claims20
A monolithic silicone, comprising a continuous silicone skeleton in the form of an aerogel or a xerogel containing continuous through pores,
- the continuous silicone skeleton also comprising a copolymerized silane of both a bifunctional alkoxysilane and a trifunctional alkoxysilane or tri- or higher functional alkoxysilanes, forming a Si—O network,
- wherein one or more of two functional groups of the bifunctional alkoxysilane, other than alkoxy groups, are selected from the group consisting of a phenyl group, a fluoroalkyl group, a vinyl group and a mercaptopropyl group.
A method for producing a monolithic silicone comprising a step of:
- copolymerizing silanes of both a bifunctional alkoxysilane and a trifunctional alkoxysilane or tri- or higher functional alkoxysilanes used as starting materials through a sol-gel reaction, whereby forming a Si—O network and causing phase separation,
- producing an aerogel or a xerogel having continuous through pores and a silicone skeleton capable of absorbing chemical species,
- wherein one or more of two functional groups of the bifunctional alkoxysilane, other than alkoxy groups, are selected from the group consisting of a phenyl group, a fluoroalkyl group, a vinyl group and a mercaptopropyl group.
