The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm
本論文以開發無機?有機復合納濾膜為出發點，首先在al _ 2o _ 3多孔微濾膜上利用溶膠?凝膠法制備sio _ 2 al _ 2o _ 3無機復合超濾膜作為無機?有機復合納濾膜的基膜；選用聚乙烯醇和聚酰胺為表面功能層材料，分別探討了以羥基丁二酸和磺基水楊酸為混合交聯劑，採用浸塗法制備了聚乙烯醇sio _ 2 ? al _ 2o _ 3復合納濾膜；以均苯二甲酰氯、哌嗪和二胺為單體，採用界面聚合法制備了聚酰胺sio _ 2 ? al _ 2o _ 3復合納濾膜，並對影響膜性能的諸多因素進行系統研究。 -
