With the amount of ch3sicl2 increased , however , the linear molecule and orbicular organic compounds containing si , o and n element were formed , which resulted decrease of gasification velocity of precursor and purity of si - c - n nano - powders 而fis樸。柱狀晶在長大過程中與相鄰的ps柞。柱狀晶相互靠近、搭接,限制了玻璃相的滑移,提高了復合材料的高溫強度。
The theory hypothesis of " pore restriction " is first proposed in this paper . during polymerization , one end of linear molecule inserts the channels of zeolite to form hard end through chemical bond or supermolecule acting force , the other end forms soft end through condensing or polymerizing with other monomer molecule . on the basis of the theory hypothesis , a kind of novel pattern of organic - inorganic composite materials - pu / zeolite composite materials - has been designed 本文首次提出了“孔約束”的理論假說,即在高分子材料聚合過程中,線型分子的一端通過化學鍵或超分子作用力插入分子篩的孔道中形成硬端,而另一端則與其它單體分子縮合或聚合形成高分子材料的軟端;在此假說的基礎上,設計了一類孔約束型有機?無機復合高分子材料的新模式,即聚氨酯/沸石分子篩復合材料。
