| Abstract: | The surface of polypropylene(PP) membrane was modified by low temperature plasma with ammonia.The effect of exposure time was investigated by means of contact angle measurement.The results show that low temperature ammonia plasma treatment can enhance its hydrophilicity.Chinese hamster ovary(CHO)cells attachment on the modified membrane was enhanced and the growth rate on the membrane was faster than unmodified one. |
