Preparation and Characterization of Poly(Lactic Acid)/Wood Flour Modified with Cyanuric Chloride/Oleyl Amine Composites
摘要
Abstract
Raw wood flour (RWF) was modified with cyanuric chloride (TCT),and the modified wood flour (TWF) and oleyl amine (OAM) were used to prepare composites with poly(lactic acid) by reactive extrusion.FT-IR spectra indicated that the structure of TCT was attached to wood flour and OAM was grafted onto TWF in the progress of reactive extrusion.Elemental analysis and titration analysis showed that the molar ratio of nitrogen and chlorine of TWF was 2.91: 1 and two of three active chlorine of TCT were involved in the reaction.The addition of OAM led to the degradation of PLA.However,the degradation of PLA/TWF/OAM composites was weaker than that of PLA/RWF/OAM composites.PLA/TWF/OAM composites exhitbited better tensile strength and flexural strength than that of PLA/RWF/OAM composites under the same dosage of OAM.PLA/TWF/OAM composites had a greater melt flow rate than that of PLA/TWF composites under the same dosage of wood flour.DMA revealed that PLA/TWF/OAM composites had a higher glass transition temperature than that of PLA/RWF/OAM composites under the same dosage of OAM.关键词
