Study on Blood Compatibility of SIS Modified by Plasma Surface Grafting

Abstract:

In this paper, water-soluble polymer PEG of different molecular weight was grafted on the SIS films by plasma surface grafting modification. These surface modifed SIS films were characterized by contact angle measurement, ATR-FTIR and XPS. The contact angle of water decreased significantly while the surface free energy and hydrophilicity increased. The relative ratio of oxygen to carbon increased from 0.06 to 0.21 . All the results revealed that the PEG molecules were incorporated onto the surface of the SIS films through covalent bonds and the surface properties changed to some extent. The blood compatibilities of the surface-modified SIS films were examined using APTT, APTT of the SIS-PEG2000 exhibted the best blood compatibility
