【摘要】 用八甲基环四硅氧烷(D4)与N,N-二甲基-γ-氨丙基-γ-氨丙基二甲氧基硅烷等进行聚合反应,合成了一种N,N-二甲基-γ-氨丙基-γ-氨丙基聚二甲基硅氧烷(ASO-121)柔软剂,用红外光谱、核磁共振氢谱、原子力显微镜等仪器对其结构和成膜形态进行了研究。结果表明,ASO-121能在棉纤维织物和单晶硅表面形成疏水膜,该膜表面略显粗糙,在2μm2扫描范围内其均方根粗糙度达到了0.226 nm。更多还原

【Abstract】 A new softener,N,N-dimethyl-γ-aminopropyl-γ-aminopropyl polysiloxane ASO-121 is synthesized by copolymerization of octamethylcyclotetrasiloxane（D₄） with N,N-dimethyl-γ-aminopropyl-γ-aminopropyl methyl dimethoxysilane and other monomers.Chemical structure and film morphology of the new synthesized polysiloxane are characterized and investigated by IR,（）¹H-NMR atomic force microscope（AFM） and other instruments.Experiment results indicate that ASO-121 can be formed a hydrophobic,some coarse structural film on the surface of the treated fabrics or silicon wafer.In 2 μm² scanning region,the film average roughness of ASO121 reaches to 0.226nm.更多还原
