Abstract
Allyl alcohol plasma polymerization permits to obtain a thin deposited film on to P(HB-co-9% HV) surface. The oxygen atomic increase is weak but gives an increase of Cls in CO, C-OC, C-OH bonds which is determinate by XPS analysis and a wettability greater than that of the non-treated material. The wettability decreases with storage temperature and time after treatment then it is stable. However it remains constant at − 20°C. The interpretation is supported by polar groups motions on the surface and the formation of a non-crosslinked deposited film whose the glass temperature value would be situated between −20 and 25°C. © 1997 Elsevier Science Ltd.
