Abstract

Bleaching treatment of kenaf fiber was performed in alkaline medium containing hydrogen peroxide solution maintained at pH 11 and 80 °C for 60 min. The bleached kenaf fiber was analyzed using Fourier Transform Infrared (FTIR) and X-ray Diffraction (XRD) analysis. The bleached kenaf fiber was then compounded with poly-(lactic acid) (PLA) via a melt blending method. The mechanical (tensile, flexural and impact) performance of the product was tested. The fiber treatment improved the mechanical properties of PLA/bleached kenaf fiber composites. Scanning electron micrograph (SEM) morphological analysis showed improvement of the interfacial adhesion between the fiber surface and polymer matrix.

摘要

在含有过氧化氢溶液的碱性介质中对红麻纤维进行漂白处理，该碱性介质的pH值保持在11，温度为80℃，持续60分钟。使用傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）分析对漂白后的红麻纤维进行分析。然后通过熔融共混法将漂白后的红麻纤维与聚乳酸（PLA）进行复合。对产品的机械性能（拉伸、弯曲和冲击）进行测试。纤维处理改善了聚乳酸/漂白红麻纤维复合材料的机械性能。扫描电子显微镜（SEM）形态分析表明，纤维表面与聚合物基体之间的界面粘附性得到了改善。
