利用氧、氮低温等离子体对醋酸纤维素超滤膜进行表面改性的比较

COMPARISON THE ABILITY OF CELLULOSE ACETATE ULTRA FILTRATION MEMBRANE TREATED BY LOW-TEMPRETURE OXYGEN PLASMA OR LOW-TEMPRETURE NITROGEN PLASMA

醋酸纤维素超滤膜经氧、氮等低温等离子体处理后，能在适宜条件下保持原有截留率的基础上，提高透水率。但氧低温等离子体比氮低温等离子要温和一些。

The water penetration of cellulose acetate ultra filtration membrane under low - tempreture oxy-gen and low - tempreture nitrogen plasma treatment was increased without cutting down the entrap-oing character. The results showed O, plasma appears to be a little more than gentle N2 plasma.
