氨基硅与羧基硅超分子膜形貌及其应用性能

以N-β-氨乙基-γ-氨丙基聚二甲基硅氧烷（ASO-1）和羧烃基聚硅氧烷（CAS-2）作为构筑基元，获得了单晶硅表面的ASO-1/CAS-2超分子膜，用原子力显微镜（AFM）等仪器研究了超分子膜形貌及应用性能。结果表明, 氨基硅和羧基硅超分子膜（ASO-1/CAS-2）明显呈规则有序的窗棂状形貌。应用性能测试结果表明,随着ASO-1比例的增加，织物的柔软性不断提高，但是织物的白度和吸湿性却降低。当ASO-1与CAS-2质量比为1∶1时，所得的织物的柔软性最好且具有独特的油润手感。基于不同黏度ASO-1所构筑的超分子ASO-1/CAS-2整理织物其白度及吸湿性差别不大，但柔软性却随ASO-1黏度的增大而提高。

Morphology of supramolecular film of amino polysiloxane and carboxyl polysiloxane and its application properties

Using N-β-aminoethyl-γ-aminopropyl polysiloxane (ASO-1) and carboxyl groups containing polysiloxane (CAS-2) as architecture units, a self-assembled supramolecular film of ASO-1/CAS-2 on the monocrystalline silicon was prepared. Its morphology and the application properties were investigated by atomic force microscope (AFM) and other instruments. Experimental results showed that the supramolecular film (ASO-1/CAS-2) showed a highly ordered, window grating-like structure. The application test indicated that when the proportion of ASO-1 increased, the softeness of the treated fabric was improved, while the whiteness and the water absorption decreased. When the ratio of ASO-1 to CAS-2 was 1∶1, the treated fabric exhibited the best softness and unique silky hand. In addition, the fabrics treated by the supramolecular ASO-1/CAS-2 based on various viscosity of ASO-1 showed almost the same whiteness and water absorption. However, the softenss was improved as the viscosity of ASO-1 increased.
