Morphology and performance of polyether block aminopolysiloxane

The morphology and chemical structure of linear polyether block aminopolysiloxane(BPEAS) assembled on the silicon were investigated by atomic force microscope(AFM) and X-ray photoelectron spectroscopy(XPS) and its performance on the fabric were studied comparatively.The results indicated that BPEAS has formed a film with a heterogeneous microstructure,and its morphology mainly consists of continuous phase formed by polydimethyl siloxane and tiny bulges formed by polyether amino groups.Application experiments showed that softness of the fabric treated by BPEAS improved obviously,and BPEAS renders cotton fabrics the best performance when compared with N-β-aminoethyl-γ-aminopropyl polydimethylsiloxane(ASO-1) and polyether silicone oil,such as epoxy/polyether modified silicone oil(CGF).
