Abstract:

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.
