Abstract
Inorganic substrates with a hydrophobic surface layer of a fluorinated material having the following structure are disclosed: where A is an oxygen radical or a chemical bond; n is 1 to 20; Y is H, F, CnH2n+1 or CnF2n+1; X is H or F; b is at least 1, m is 0 to 50, and p is 1 to 20. The fluorinated material can be directly adhered to the inorganic substrate or can be indirectly adhered to the inorganic substrate through an intermediate organometallic coating.
Claims29
An inorganic substrate with a surface layer of a fluorinated material having the following structure:
- where A is an oxygen radical or a chemical bond;
- n is 1 to 6;
- Y is H, F, CnH2n+1 or CnF2n+1;
- X is H or F;
- b is 5-12, m is 1 to 6, p is 2 to 4, and Z is an acid group or an acid derivative.
A method of depositing a fluorinated material on an inorganic substrate surface comprising:
- (a) contacting the surface either directly or through an intermediate organometallic layer with a fluorinated material in a diluent, in which the fluorinated material has the following structure:
- where A is an oxygen radical or a chemical bond;
- n is 1 to 6;
- Y is H, F, CnH2n+1 or CnF2n+1;
- X is H or F;
- b is 5-12, m is 1 to 6, p is 2 to 4, and Z is an acid group or an acid derivative;
- (b) forming a film on the substrate.
