The preparation and properties of wood flour/high density polyethylene composites by in-situ reaction extrusion

The technique of grafting silane by in-situ extrusion to improve the compatibility between wood flour and high density polyethylene (HDPE) composites was studied. it was found that the silane grafted composites showed enhanced mechanical properties compared to both the coupled and non-coupled PE-g-MAH composites. The effects of silane contents and dicumyl peroxide (DCP) concentrations on the mechanical properties of the composites were investigated in detail. Moreover, the water absorption, morphology and thermal stability of the composites were also investigated. Copyright (C) 2008 John Wiley & Sons, Ltd.
