Creation of novel anisotropic composites from renewable materials

对弱磁性材料的晶体结构分析、高技术材料的制备、基于磁效应的取向分析等方面进行了研究。(A)纸浆/无机填料各向异性复合材料的制备及其力学性能分析。(B)纤维素微纤维的三维排列。硬磁化轴是对齐的，而其他两个轴是低对齐的。为了更好地对齐，需要缩小纤维尺寸。(C)进行了磁取向的现场测量。利用这一技术，我们发现纤维素纤维的磁各向异性随着纤维尺寸的减小而增加。用该方法测定了各向异性磁化率。

The study was carried out on the crystal structure analyses, fabrication of high-tech materials, and analysis of alignment on the basis of magnetic effects on feeble magnetic materials. (A) Preparation of anisotropic composites of pulp/inorganic fillers and its analysis of mechanical properties. (B) 3-dimensional alignment of cellulose microfibrils. The hard magnetization axis was aligned but the other two axes exhibited low alignment. Downsizing of fibers needed for better alignment. (C) In-situ measurement of magnetic alignment was performed. Using this technique, it was found that magnetic anisotropy of cellulose fibers increases upon downsizing fibers. Anisotropic magnetic susceptibilities were determined using this method.
