Fully biodegradable bamboo fiber and polylactide composites

초록

Bamboo fiber may withhold great potential as an alternative to wood, and bamboo can be a raw material to fabricate a composite material and its applicability is being widely investigated. Cellulose fibers can be aligned to the length of the bamboo providing maximum tensile and flexural strengths and rigidity. Increased research in the recent years has considerably contributed to the use of bamboo fibers as a reinforcing material for broader applications. However, it is difficult to obtain polymer/bamboo fiber composite having its excellent mechanical properties, because the bamboo fibers covered with lignin show lack of interfacial adhesion. Therefore, it is necessary to enhance the interfacial adhesion by extracting lignin without microstructure disruption and adding silane coupling agents. In this research the influence of silane coupling agent, composites with pristine bamboo fiber, delignified bamboo fiber, and delignified and silane treated bamboo fiber were newly prepared and investigated, respectively.
