Abstract: Preparation of the novel biodegradable composite based on carboxymethyl derivatives of starch and cellulose as well as microcrystalline cellulose was described. The effect of filler content (1–7 phr) on the physicochemical properties (moisture sorption, water solubility, mechanical properties) of the resulting films was determined. With the filler amount increase the Young’s modulus increased from 4.8 up to 32.4 MPa, while the solubility in water dropped from 64 to 58%, for the system without, and containing 7 phr microcrystalline cellulose, respectively.

Keywords: Carboxymethyl starch ; Carboxymethyl cellulose ; Microcrystalline cellulose ; Natural composite ; Biodegradable film
