摘要: A study on oxygen plasma functionalization of polyethyleneterephthalate (PET) is presented. Samples were exposed to a weakly ionized, highly dissociated RF oxygen plasma with an electron temperature of 5eV, a density of positive ions of 8× 1015m− 3 and a density of neutral oxygen atoms of 4× 1021m− 3. The oxygen pressure was 75Pa and the discharge power was 200W. The wettability of plasma-modified samples was determined by measuring the contact angle of a water drop, while the appearance of the functional groups …
