Novel organic-inorganic hybrids based on cellulose acetate butyrate (CAB) were synthesized applying sol-gel process. The inorganic phase was introduced into polymer matrix by hydrolysis and condensation using tetraethoxysilane (TEOS) as the precursor, under acidic conditions. The obtained organic-inorganic hybrids were characterized by different techniques such as IR spectroscopy, thermogravimetric analysis (TGA), solid state 29Si NMR and scanning electron microscopy (SEM). Organic-inorganic hybrids obtained with 20% of diethyl phthalate (DEP) as plasticizer exhibit good transparency in comparison with unmodified CAB.
Key words: cellulose acetate butyrate, sol-gel process, organic-inorganic hybrids, thermogravimetric analysis, IR spectroscopy, 29Si NMR, scanning electron microscopy
