摘要
微胞孔聚四氟乙烯膜汤祟正，徐镰祥，汤立聪（华南理工大学材料科学研究中心广州５１０６４１）（华南理工大学自动化系）关键词空气过滤膜，微孔泡沫－聚四氟乙烯，压力引导相分离，等离子体聚合一般泡沫制品如聚氨脂等孔径在１．８—０．１５ｍｍ之间，与此完全不同范畴...
According to mechanism of pore formation,micro-and ultramicro-cellular polytetraflouroethylene porous membrances were prepared with classical dispersion.gelation and pressure-induced phase separation method, and characterized by scanning electron microscope.electron spectroscopy for chemical analysis.differential scanning calorimeter and bubling method. The results show that the membranes through pressure-induced phase separation and plasma polymerization with ethylene are easy to control and have good characteristics.
