BAMBOO-CONTAINING COMPOSITES WITH ENVIRONMENTALLY FRIENDLY BINDERS

The environmentally friendly binder - poly [(trimethoxy)4-vinylphenethyl)] silane was synthesized for the first time via Friedel-Crafts alkylation reaction, which was conducted by the reaction of polystyrene with vinyltrimethoxysilane in the presence of anhydrous AlCl3. The synthesized polymer was identified using 1H, 13C, 1H COSY NMR, and FTIR spectroscopy. Bamboo sawdust -based composites with various dispersion properties have been created using synthetic trimethoxysilylated polystyrene (TMSPSt) and styrene with various degrees of silylation (5-10%). Composite materials based on bamboo powder with various organic/inorganic additives, flame retardants, and antioxidants, were processed at different temperatures and pressures using the hot pressing method. Obtained composites were studied by Fourier transformation infrared spectroscopy (FTIR), optical and scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). Thermal stability of the obtained materials was determined by thermogravimetry and the Vicat method. Also, water absorption and some mechanical properties were studied.
