中文摘要	Polytetrafluoroethylene films are treated by room temperature helium atmospheric pressure plasma plumes, which are generated with a home-made single liquid electrode plasma device. After plasma treatment, the water contact angle of polytetrafluoroethylene film drops from 114 to 46 and the surface free energy increases from 22.0 mJ/m(2) to 59.1 mJ/m(2). The optical emission spectrum indicates that there are reactive species such as O-2(+), O and He in the plasma plume. After plasma treatment, a highly crosslinking structure is formed on the film surface and the oxygen element is incorporated into the film surface in the forms of -C-O-C-, -C=O, and -O-C=O groups. Over a period of 10 days, the contact angle of the treated film is recovered by only about 10 degrees, which indicates that the plasma surface modification is stable with time.
