在温和条件下，以３－氨丙基三乙氧基硅烷为偶联剂，修饰介孔分子筛 ＭＣＭ－４１（Ｓｉ／Ａｌ＝３５），成功地将有机官能团引入到介孔分子筛孔道中，制备了一种无机一有机复合材料ＭＣＭ－（ＣＨ２）３ＮＨ２，以 ＸＲＤ、ＦＴＩＲ、ＤＴＡ－ＴＧＡ、 Ｎ２吸附－脱附和 ＨＲＥＭ表征了复合材料；结果表明：有机基团－（ＣＨ２）３ＮＨ２不仅进人孔道、修饰了ＭＣＭ－４１的孔壁，而且使介孔分子筛ＭＣＭ－４１保持了有序的孔道结构．
Under mild experiomental conditions, with 3-aminopropyltriethoxysilane as the coupling agent, mesoporous molacular sieve MCM--41(Si/Al=35) was modified,
and --(CH2)_3NH2 organic functional group was successfully introduced into the pore of the mesoporous sieve, the organic/inorganic complex material MCM--(CH2)3NH2
was synthesized, and characterized by XRD, FTIR, DTA-TG, nitrogen adsorption-desorption at 77K and HREM. The results of the characterization show that --(CH2)3NH2
not only gets into the modified inner wall of mesoporous MCM-41, but also makes MCM--41 remain its ordered pore structure.
