Multi-wall carbon nanotubes/konjac glucomannan composites（OMWNT/KGM） were prepared by blending oxidized multi-wall carbon nanotubes and KGM.FT-IR,SEM（scanning electron microscope）,TG（thermogravimetry analysis）,DMA（dynamic mechanical analysis）and mechanical test were performed.The effects of OMWNT content on composites were investigated.The results indicated that there existed molecular interaction and thermal and mechanical properties of OMWNT/KGM were improved with the addition of OMWNT. 多壁碳纳米管 魔芋葡甘聚糖 复合材料 热性能 力学性能 MWNT（multi-wall carbon nanotubes） KGM（konjac glucomannan） composites thermal properties mechanical properties TB383.1 湖北省教育厅重点科研项目资助（D200625004） 2008-02-01 2021-04-01 2
