Characterization of the Chemical, Physical, and Mechanical Properties of NaOH-treated Natural Cellulosic Fibers from Corn Husks

ABSTRACT

This paper focuses on the chemical, physical, and mechanical properties of corn husk fibers treated with different concentrations of NaOH (0.5%, 1%, 2%, 5%, and 8%) for 2 h. The results show that treatment with NaOH removed the hemicellulose and lignin in the fibers and decreased the moisture content. Consequently, the chemical, physical, and mechanical properties of the treated fibers were greatly improved. Scanning electron microscopy analysis indicated the presence of rough surfaces and a number of lumens inside the fiber bundles. The results suggest that the treated corn husk fibers exhibited better mechanical properties than fiberglass.

摘要

本文主要对化学，物理，和玉米皮纤维与不同浓度的NaOH处理后的机械性能（0.5%，1%，2%，5%,和8%）2小时，结果表明，处理NaOH去除半纤维素和木质素纤维和水分含量降低。因此，经过处理的纤维的化学、物理和机械性能都得到了极大的改善。扫描电子显微镜分析表明存在粗糙的表面和纤维束内部的若干流明。结果表明，经过处理的玉米壳纤维具有比玻璃纤维更好的力学性能。
