PLASMA TREATMENT OF UHMWPE FIBERS

摘要

摘要: 研究了超高分子量聚乙烯纤维的低温等离子表面处理。经低温等离子处理,超高分子量聚乙烯纤维对乙二醇的浸润性提高,接触角降低,纤维表面产生了活性自由基,纤维对亚甲基蓝的吸附性增强。等离子处理使纤维含氧量增加,表面产生沟槽,比表面积增大,纤维/环氧复合材料的层间剪切强度提高3倍以上。

Abstract: The surface of UHMWPE fiber was treated by a low temperature plasma. After the plasma treatment, the wetting power of UHMWPE fiber to ethylene glycol is improved and the contact angle is reduced. The active free radicals are produced on the fiber surface and the absorbability to methene blue is enhanced. The plasma treatment makes the fiber increase the oxygen content and surface area. The ILSS of UHMWPE/epoxy composite is enhanced more than 3 times.
