Abstract:
PCT No. PCT/GB91/02180 Sec. 371 Date Aug. 4, 1992 Sec. 102(e) Date Aug. 4, 1992 PCT Filed Dec. 9, 1991 PCT Pub. No. WO92/10532 PCT Pub. Date Jun. 25, 1992.Surfaces of polymers, particularly polyesters, can be fluorinated by deposition of a fluorocarbon from solution. The fluorocarbon may be an amorphous fluoropolymer, such as the copolymer of tetrafluoroethylene and bis-2,2-trifluoromethyl-4,5-difluoro-1,2-dioxole sold under the trademark TEFLON AF TM , which is soluble in fluorinated alkanes and other fluorinated liquids such as those sold under the trademark FLUORINERT TM . Surface-fluorinated polyesters, particularly in knitted fabric form, are useful as vascular grafts: the fluorinated surface reduces thrombogenicity and complement activation. The disadvantages of known surface fluorination methods, such as the cold plasma or glow discharge process, are avoided.
