Chitin nanofibers were prepared from dried crab shells by a simple grinding treatment in a never-dried state under n acidic condition after the removal of proteins and minerals. The obtained nanofibers were observed by FE-SEM and ound to have a uniform width of approximately 10-20 nm and high aspect ratio; both these findings were similar to hose for nanofibers from prawns. Furthermore, it was confirmed that the nanofibers were extracted from the aturalchitin/protein/mineral composites of crab shell in their original state. That is, the N-acetyl group was not emoved and the chitin crystal structure was maintained, as confirmed by elemental analysis data, FT-IR spectra, and X-ray diffraction profiles.Optically transparent chitin nanofiber composites were fabricated with acrylic resins. Chitin nanofibers rastically increased the Young's moduli and the tensile strengths, and decreased the thermal expansion of all acrylic resins due to the reinforcement effect of chitin nanofibers having an extended crystal structure.

以干燥蟹壳为原料，去除蛋白质和矿物质后，在酸性条件下，在未经干燥的状态下，通过简单的研磨处理制备了甲壳素纳米纤维。通过FE-SEM和声音观察到所获得的纳米纤维具有约10-20 nm的均匀宽度和高纵横比;这两个发现与来自对虾的纳米纤维的软管相似。进一步证实了纳米纤维是从天然蟹壳甲壳素/蛋白质/矿物复合材料中提取的。通过元素分析、红外光谱和X射线衍射分析，证明了甲壳素的N-乙酰基没有被去除，甲壳素的晶体结构保持不变。甲壳素纳米纤维的拉伸强度和杨氏模量急剧增加，并由于具有扩展的晶体结构的甲壳素纳米纤维的增强效果，降低了所有丙烯酸树脂的热膨胀。
