Polypropylene/Wood Flour Composites Prepared by Solid State Shear Milling

Abstract:

In this paper, solid state shear milling method was successfully employed to prepare polypropylene/wood flour composites (WPC) and their structure and performances were investigated. The experimental results showed through solid state shear milling, the aggregates of wood fiber were broken down and polymer closely adhered to wood fiber, which improved the dispersion of wood fiber and the interfacial interaction between PP and wood fiber. As a result, the performances of WPCs in this way were more excellent than that of WPCs by the conventional method. This study could provide a novel approach to resolve the problems of the dispersion, stabilization and compositing of wood flour with polymer matrix and prepare WPC with higher performances.
