【摘要】 开发具有某种功能的复合材料就要对材料结构进行相应的设计。微纳多层共挤出技术是通过简单地对高分子熔体进行分割-变流-合并过程来增加层数。微纳交替多层结构的复合材料。在结构上不同传统加工方法得到的复合材料,其力学性能、阻隔性能、导电性能、光学性能等具有独特的优点。微纳多层共挤出技术还可用于开发新型的中间相材料。此外,这种交替多层结构形态为界面张力、粘接、结晶、扩散等理论研究提供了一个很好的模型。更多还原

【Abstract】 It’ s necessary to design the structure of a material for preparing a composite with corresponding function. The number of layers is increased through slicing-flow changing-combining the polymer melt by micro- or nano-Layer coextrusion, and the micro- or nano-Layer alternative structure is designed. The properties of the composites with micro- or nano-Layer alternative structure are different from the conventional processing products, such as mechanical property, barrier property, conductivity, optical property etc. Micro- or Nano-Layer coextrusion can also be used to develop the interphase materials. Moreover, a wonderful model, which is used for the research on interface tension, adhision, crystallization, diffusion etc, was supplied by the alternative multilayer strcuture.更多还原
