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 softness 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 with unique oily handle.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 softness was improved as the viscosity of ASO-1 increased.
