An influence of water absorption on wettability was studied for acryl resin for biomedical applications. Water absorption at boiling point enhanced the wettability on acryl resin surface. The wettability was evaluated by using contact angle of sessile drop. Water absorption decreased the contact angle. Based on extended Fowkes theory, the influence of water absorption on the wettability was explained. The bonding between absorbed water and (COOCH3) molecules decreased the hydrogen bond strength in acryl resin and then enhanced the wettability.
