采用高剪切工艺制备了一种具有独特分层结构的导电聚偏氟乙烯(PVDF)/聚酰胺6 (PA6)/碳纳米管（CNTs）复合材料。PVDF与PA6基本形成共连续结构。碳纳米管完全位于PA6相中，而许多尺寸从10到150 nm的PA6结构域分散在PVDF相中。研究了复合材料的物理性能（如电导率和机械性能）与形貌之间的关系。结果表明：通过高剪切处理在PVDF相中形成PA6纳米结构域，不仅提高了共混纳米复合材料的导电性，而且提高了其延展性。
A conductive poly(vinylidene fluoride) (PVDF)/polyamide 6 (PA6)/carbon nanotubes (CNTs) composite with a unique hierarchical morphology has been fabricated by the dual formation of cocontinuous and nanodispersion structures using high-shear processing. PVDF and PA6 basically forms cocontinuous structure. The CNTs are exclusively located in the PA6 phase, and numerous PA6 domains with the size ranging from 10 to 150 nm are dispersed in the PVDF phase. The relationships between the physical properties (e.g., electrical conductivity and mechanical properties) and morphology of the composite have been investigated. The results indicate that the formation of PA6 nanodomains in PVDF phase by the high-shear processing not only increases the electrical conductivity but also improves the ductility of the obtained blend nanocomposites.
