Films of Poly(ethylene oxide), PEO, were modified to impart hydrophilicity via UV irradiation. The UV
irradiation treatment produced new photo-oxidized groups of carbonyl and ether groups as indicated in ATR and ESCA
analysis. It was found that water contact angle decreased from 15° to 10° and total surface energy of PEO increased from
54.2 mN/m to 76.6 mN/m with increasing UV energy, which was attributed to significant contribution of acid base
interaction of the photo-oxidized PEO rather than nonpolar interaction originating from the dominant increase in Lewis acid
parameter. The increased hydrophilicity and surface energy were also proved by the decreased water wetting time |
