Abstract:
A method of making a laser ablated article, comprisingforming an article of one or more layers, wherein each of the layers absorbs radiation within the wavelength range of from about 210 nm to about 360 nm, wherein at least one of the layers comprises a hydrophobic fluorine-containing graft copolymer derived from at least one fluorine-containing monomer selected from the group consisting of tetrafluoroethylene, perfluoro(vinyl ether) and hexafluoropropylene and at least one comonomer containing at least one aromatic group and having a structure wherein each of X1, X2, X3, X4, X5 and X6 are the same or different and are selected from the group consisting of H, an alkyl group having from 1 to 20 carbon atoms and an aryl group having from 6 to 18 carbon atoms and wherein at least one of X1, X2, X3, X4, X5 and X6 is not H, and wherein the comonomer is present in an amount of about 0.5% to about 20.0% based on the weight of the comonomer and the fluorine-containing monomer, andprocessing the article with a laser that outputs radiation at a wavelength of between about 210 nm and about 360 nm.
