Thermo-Chemical Evaluation of Wood Plastic Nanocomposite

摘要：

Most applications expose the materials to wide range of temperatures,which may influence on thermal behavior of materials.Thermal degradation of wood polymer composites(WPCs)is a crucial aspect for application and manufacturing process of these products.In this research,wood polymer composites with different nanoclay contents were prepared by melts compounding method.The amount of wood flour and coupling agent were fixed at 40％ and 10％ wt％(total weight),respectively,and the different levels of nanoclay include 0,3 and 5％ wt％ were used in preparing the composites.Thermal properties of nanocomposites were characterized by Differential Scanning Calorimeter(DSC)and thermal gravimetric analysis(TGA).The DSC analyses show that the crystallization temperature(Tc),enthalpy △Hm,and the degree of crystallinity(Xc)of the nanocomposites were increased by addition of nanoclay.The TGA results indicate that by increasing the nanoclay percentage the degradation temperatures and thermal stability was enhanced.
