Reactivity of (3-aminopropyl)trimethoxysilane with cellulose
Reactivity of (3-aminopropyl)trimethoxysilane with cellulose. The paper presents the results of tests for the reactivity of (3-aminopropyl)trimethoxysilane (APTMOS) with cellulose. The cellulose was treated with aqueous ethanolic solution of silane in two concentration: 5% and 20%. The reactivity of APTMOS with cellulose was analysed using instrumental methods: attenuated total reflectance Fourier transform infrared spectroscopy, atomic absorption spectrometry and elemental analysis. In the FTIR spectra of silane-treated cellulose, the bands of Si-O, Si-C and N-H bonds were detected. The analysis of silicon and nitrogen concentration in treated cellulose confirmed the presence of silane in cellulose structure. The presented results indicate that APTMOS forms chemical bonds with cellulose.
