研制出一种高选择性的管式硅基裂解膜；并报道了这种膜的制备方法．这种膜是由分子规则排列的硅树脂材料经裂解制成，对Ｈ２渗透系数达１０４Ｂａｒｒｅｒ，Ｈ２／Ｎ２分离因子１６．８，其选择透过性能优于常规的有机膜和无机膜，也优于由分子无规排列的硅树脂所制成的裂解膜．这种膜制备方法简单、价廉、重现性好．
Developed a highly selective tubular silicon-based cracking film; and reported the preparation of this film. This film is made by the molecular arrangement of the silicone material by cracking the permeability coefficient of H2 up to 104Barrer, H2 / N2 separation factor of 16.8, the choice of permeability better than conventional organic and inorganic membranes, also excellent Ligands made of randomly oriented molecules of silicone. This membrane preparation method is simple, inexpensive, reproducible.
