摘要

将聚乙二醇(PEG)基聚氨酯(PU)及其与聚甲基丙烯酸甲酯(PMMA)的半互穿聚合物网络(SIPN)涂覆在碱处理和未经碱处理的竹纤维(Bambusa balcooa)表面。研究了涂覆PU和PU/PMMA SIPN前后竹纤维的抗拉强度、抗拉模量、耐化学性等力学性能。竹纤维经聚合物涂层后，拉伸强度、拉伸模量和耐化学性均有提高。与PU包覆竹纤维复合材料相比，PU/PMMAcoated体系表现出更好的性能。

Studies on Bamboosa Balcooa bamboo fibre for green composites with polyurethane and polyurethane/poly(methyl methacrylate) semi-interpenetrating polymer network

The poly(ethylene glycol) (PEG)-based polyurethane (PU) and its semi-interpenetrating polymer network (SIPN) with poly(methyl methacrylate) (PMMA) have been coated on the surface of alkali-treated and untreated bamboo fibres (Bambusa balcooa). The mechanical properties, like tensile strength and tensile modulus, and the chemical resistance of bamboo fibres before and after coating with PU and PU/PMMA SIPN have been studied. Improvement in tensile strength, tensile modulus and chemical resistance of bamboo fibres were observed after coating with polymers. The PU/PMMAcoated system showed better performance as compared to PU-coated bamboo fibre composite.
