Acrylonitrile-butadiene-styrene copolymer (ABS)/cellulose composites were prepared by melt compounding with a twin screw extruder. Maleic anhydride grafted styrene-acrylonitrile copolymer (SAN-MAH) was used to improve the interaction and adhesion between the hydrophobic matrix and the hydrophilic natural fibers. Mechanical properties of ABS decreased with increase in the cellulose content of ABS/cellulose composites. Incorporation of SAN-MAH into ABS/cellulose composites raised the tensile properties of the composites. Moreover, Izod impact test results revealed that SAN-MAH played a vital role in the improvement of the impact strength of ABS/cellulose composites. The results of the tensile tests were rationalized by the morphology of the composites observed by a scanning electron microscope. The degree of dispersion of cellulose fibers was better in ABS/SAN-MAH/cellulose than in ABS/cellulose composite. |
