Major research results of this projects entitled with "Research about fictionalization of composites including a small amount of vapor grown carbon fiber by magnetic or electric field" are the following points :1.Fundamental orientation property of vapor grown carbon fiber(VGCF)1.1 Establishment of dispersion method and length analysisVGCFs as received has lump structure but a simple dispersion method was established without breaking VGCFs, resulting in the possibility of measurement of VGCF length and its distribution. The length change during melt mixing was quantitatively analyzed. The electric conductivity of composites was evaluated. The relationship among length of VGCFs, electric conductivity, melt mixing were investigated1.2 Fundamental orientation property under magnetic fieldThrough rotational speed analysis of a single VGCF (well dispersed state, very low concentration) in polymeric matrix, magnetic anisotropic property was determined. In addition, structural development of VGCF under magnetic field was investigated1.3 Fundamental orientation property under electric fieldThrough rotational speed analysis of a single VGCF (well dispersed state, very low concentration) in polymeric matrix, magnetic anisotropic property was determined. In addition, structural development of VGCF under electric field was investigated2.Development of magnetic or electric processing apparatusMatch type magnetic or electric processing apparatus was developed and it was demonstrated to produce polymeric film including VGCFs oriented under magnetic or electric field. The films show transparent electro conductive (thickness direction about 10ohm-cm, only with 0.2wt% of VGCFs) property.

本项目“含少量气相碳纤维复合材料磁场或电场虚构化研究”的主要研究成果如下：1。1.1色散方法和长度分析方法的建立收到的VGCF具有块状结构，但建立了一种不破坏VGCF的简单色散方法，从而可以测量VGCF的长度及其分布。定量分析了熔体混合过程中的长度变化。对复合材料的电导率进行了评价。研究了VGCF的长度与电导率、熔体混合率之间的关系。1.2磁场作用下的基本取向特性。通过对聚合物基体中单个VGCF（分散良好，浓度极低）的转速分析，确定了其磁性各向异性。1.3电场作用下VGCF的基本取向特性。通过对聚合物基体中单个VGCF（分散良好，浓度极低）的转速分析，确定了其磁性各向异性。此外，还研究了电场作用下VGCF的结构发展情况。磁或电加工装置的发展研制了match型磁或电加工装置，并证明了它可以在磁场或电场下生产含vgcf的聚合物薄膜。薄膜具有透明导电性能（厚度方向约为10ω -cm，仅为VGCFs的0.2% wt%）。
