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.
