Abstract
The invention provides a method of coating a fabric, e.g. a textile material, with a polymer coating, which method comprises contacting a fabric with a monomer and subjecting the monomer to low power plasma polymerization, wherein the monomer comprises the general formula (I): CnF2n+1CmX2mCR1Y—OCO—C(R2)═CH2, wherein n is 2 to 6, m is 0 to 9, X and Y are H, F, Cl, Br or I, R1 is H or alkyl, e.g. —CH3, or a substituted alkyl, e.g. an at least partially halo-substituted alkyl, and R2 is H or alkyl, e.g. —CH3 or a substituted alkyl, e.g. an at least partially halo-substituted alkyl.
Claims17
A method of coating a fabric with a polymer coating, which method includes contacting a fabric with a monomer and subjecting the monomer to plasma polymerisation, wherein the monomer comprises the general formula (I):
- CnF2n+1CmX2mCR1Y—OCO—C(R2)═CH2
- wherein n is 2 to 6, m is 0 to 9, X and Y are H, F, Cl, Br or I, R1 is H or alkyl or a substituted alkyl and R2 is H or alkyl or a substituted alkyl, wherein the method comprises a step of outgassing the fabric in a plasma chamber before deposition of the coating in which the outgassing is performed by pumping away moisture and trapped gases from the fabric and away from the plasma chamber, whilst winding the fabric from a first roller to a second roller, and wherein the fabric is guided between said rollers during the step of subjecting the monomer to plasma polymerization in the plasma chamber.
