聚丙烯微孔膜表面的等离子体接枝
Plasma Grafting of Microporous Polypropylene Membrane
-
摘要: 通过氢气氛等离子体处理，在聚丙烯微孔膜表面接枝了聚丙烯酸，改善了膜表面的亲水性。接枝率与等离子体放电功率、放电时间和溶液浓度有关，微孔膜内外表面及不同位置接枝效率有差别。接枝后微也膜的表面孔径减少了。Abstract: Graft polymerization of acrylic acid was initiated on the surface of mi-croporous polypropylene membrane after treated in argon plasma. Polyacrylic acid was successfully grafted onto the membrane surface so that the hydrophilicity was increased. The graft
