Abstract
The present disclosure provides a hydrophobic and oleophobic film layer and a method for preparing the hydrophobic and oleophobic film layer. The hydrophobic and oleophobic film layer is prepared by plasma chemical vapor deposition from a perfluoropolyether monomer containing acrylate group(s) and a monomer containing two or mor carbon-carbon unsaturated bonds.
Claims31
A hydrophobic and oleophobic film layer, being a plasma polymerization coating formed by contacting a substrate with a plasma of a monomer α and a plasma of a monomer wherein the monomer α has a structure of formula (1),
- in formula (1), R1, R2 and R3 are respectively and independently selected from a C1-C4 hydrocarbon group or a hydrogen atom;
- R4 is selected from a C1-C4 perfluorinated alkyl group or a fluorine atom;
- and L1 is a linking group;
- and
- m is an integer greater than or equal to 1;
- each n in the m number of repeating units is respectively and independently selected from an integer greater than or equal to 1;
- and
- wherein the monomer β contains two or more carbon-carbon unsaturated bonds.
