聚硅氧烷超分子ASO-1/CPES膜及其应用性能
摘要
Based on the architecture units of N-β-aminoethyl-γ-aminopropyl polydimethylsiloxane (ASO-1) and carboxyl modified polyether-b-polydimethylsiloxane (CPES), ASO-1/CPES supramolecular film was formed on the surface of cotton fabric. The film forming performance and application were studied. Field emission scanning electron microscope (FE-SEM) investigation showed that the fabric surface anchored with ASO-1/CPES supramolecular film was much smoother than that of the control sample. Compared with the fabric treated with ASO-1 alone, the fabric with supramolecular film has better softness, whiteness and hydrophilicity. In addition, when the mass ratio of ASO-1 to CPES was 1:2, the treated fabric showed the optimum softness and certain hydrophilicity without affecting its whiteness, demonstrating the best comprehensive application performance. Besides, the suitable viscosity and amino value of ASO-1 for the suparmolecular assembly was 3650 mPa•s and 0.9 mmol/g, respectively.
