Box 737, Sari, Mazandaran, Iran aut Effect of Lignocellulosic Type on Long-Term Hygroscopic Behavior of Natural Filler/HDPE Composites [Elektronische Daten] [Seyed Zabihzadeh] Natural filler/high density polyethylene (HDPE) injection-molded composites of flour from different lignocellulosic sources were prepared, and their long-term water absorption and thickness swelling were studied. Filler samples from wheat straw, hybrid Euro-American poplar, and loblolly pine were mixed with the matrix at 35wt% lignocellulosics content and either zero or 2% maleic anhydride grafted polyethylene (MAPE) as compatibilizer. Results indicated water absorption of all the composites followed the kinetics of a Fickian diffusion process. The water diffusion coefficient of the composites was clearly dependent upon the lignocellulosic type. The wheat straw composites showed the highest and the pine composites exhibited the lowest water absorption coefficients. The highest thickness swelling took place in the wheat straw composites, followed by the poplar and pine composites, respectively. Adding MAPE to the composites decreased the water diffusion coefficient and thickness swelling by improving the adhesion between natural filler and the HDPE.
