Wettable PTFE was prepared by tretment with allyl alcohol plasma. The water contact angle is 40-60°compared with that of 118?of the untreated PTFE. Analyses by infrared spectroscopy
ESCA
and SEM show that a graft layer which contains-CH3
CH2
C = 0
and C-OH groups was formed on surface of PTFE. With the increase of treating time
the oxygen concentration decreases and contact angle increses.
