Abstract
The supramolecule CPES/ASO was self-assembled from carboxylated polyether-block-polydimethylsiloxane (CPES) and N-β-aminoethyl-γ-aminopropyl polysiloxane (ASO) in ethyl acetate solution. The film morphology and performance of CPES/ASO on cotton substrates were investigated by field emission scanning electron microscope (FESEM), atomic force microscope (AFM), X-ray photoelectron microscope (XPS), and so on. The results indicated that a polysiloxane resin film was coated on the treated fiber surface and able to decrease the root mean square roughness (Rq) of the treated fiber conspicuously. Morphology of higher peaks circled by many smaller peaks was observed on the film surface, which was partly similar to that of CPES/ASO on the silicon wafer. Besides, when the mass ratio of CPES to ASO was 2:1, the fabric treated by CPES/ASO showed the best softness and had a comfortable oily tactile.
