中文摘要:
      将废弃花生壳纤维作为一种增强材料应用到可降解高分子材料聚丁二酸丁二醇酯(PBS)中,采用熔融共混法制备了聚丁二酸丁二醇酯/花生壳纤维(PBS/F)复合材料,分析了复合材料的结晶性能、热性能及力学性能,并采用分子模拟对性能的改变进行了验证。结果表明:花生壳纤维的添加并没有改变PBS的晶型,但作为成核剂参与了PBS的结晶过程,促进了复合材料的结晶,缩短了复合材料的结晶时间。花生壳纤维含量为5%时其成核作用最强,使其作为“桥梁”镶嵌在复合材料中,结合分子间相互作用使得复合材料的热性能及力学性能较纯PBS有所增加。分子模拟结果表明了花生壳纤维与PBS形成了C=O…H-O,从而增强两者的界面结合。
英文摘要:
      Waste peanut shell fiber was used as a kind of reinforcing material in the degradable polymer material poly (butylene succinate) (PBS). The poly (butylene succinate)/peanut shell fiber (PBS/F) composite material was prepared by melt blending method. The crystallization properties, thermal properties and mechanical properties of the composite material were analyzed,and molecular simulations were used to verify the changes in properties. The results showed that the addition of peanut shell fiber did not change the crystal form of PBS, but participated in the crystallization process of PBS as a nucleating agent, which promoted the crystallization of the composite material and shortened the crystallization time of the composite material. When the peanut shell fiber content is 5%, its nucleation effect is the strongest, making it as a "bridge" embedded in the composite material, combined with intermolecular interactions, the thermal and mechanical properties of the composite material are increased compared with pure PBS. The molecular simulation results showed that peanut shell fiber and PBS formed C=O...H-O, to enhance the interface ?between the PBS and peanut shell fiber.
