Abstract
A solid material is subjected to surface treatment by chemically bonding onto a surface of the solid material a stabilized monofunctional silanol represented by R1R2R3SiOH. R1, R2 and R3 may be the same or different, and each represent a substituent group independently selected from a substituted or unsubstituted, monovalent hydrocarbon group having from 1 to 40 carbon atoms or a substituted or unsubstituted, monovalent heterocyclic group having from 1 to 100 carbon atoms. The monofunctional silanol has a dehydrative self-condensation rate lower than triethylsilanol.
Claims2
A surface treatment method for the formation of a monolayer for a solid material having hydroxyl group on its surface, comprising chemically bonding a stabilized monofunctional silanol represented by the following formula (1) onto the surface of the solid material without using any catalyst:
- R1R2R3SiOH (1)
- wherein R1, R2 and R3 may be the same or different and each represent a substituent group independently selected from a substituted or unsubstituted, monovalent hydrocarbon group having from 1 to 40 carbon atoms or a substituted or unsubstituted, monovalent heterocyclic group having from 1 to 100 carbon atoms, with a proviso that the total number of carbons of R1, R2 and R3 is at least ten and the monofunctional silanol represented by the formula (1) has a dehydrative self-condensation rate lower than triethylsilanol, to form an organosilicon monolayer.
