研究了电源功率、处理时间、反应气体用量、表面能、含水率、透过率、分配系数、扩散系数和自由体积等等离子体处理条件对尼龙4膜性能的影响。透析体系考虑的溶质为氯化钠、尿素和氯化镁。在80W的Ar中处理20min，膜对氯化钠和尿素的透过率分别为5.57×10cm2/−和5.89×10cm2/−。经氧等离子体处理的尼龙4膜在20W和20min时的渗透系数分别为30.74×10−5和17.6610−5cm2/min，明显高于未处理的尼龙4膜。
The effects of plasma treatment conditions, such as supply power, treatment time, gases used in reactor, surface energy, water content, dialysis permeability, partition coefficient, diffusion coefficient, and free volume of Nylon 4 membranes, were studied. The solutes considered for dialysis system were NaCl, urea, and MgCl2. The permeabilities of NaCl and urea of membranes with plasma treated in argon at 80 W for 20 min are 5.57 × 10−5 and 5.89 × 10−5 cm2/min, respectively. Much higher permeabilities of NaCl and urea obtained by oxygen plasma-treated membranes under 20 W and for 20 min are 30.74 × 10−5 and 17.66 10−5 cm2/min, respectively, compared to that of untreated Nylon 4 membranes.
