| 中文摘要: |
| 通过将纳米微晶纤维素(NCC)通过氢键作用吸附在还原氧化石墨烯(RGO)上,制备了纳米微晶纤维素改性的石墨烯(NCC-RGO),并将其作为填料,用溶液混合法制备了聚乙烯醇(PVA)复合膜.对复合膜的结构及其吸水率,热稳定性和力学性能进行了研究.结果表明:NCC能够有效的防止RGO的团聚,NCC-RGO能在水中稳定分散.NCC-RGO作为填料能够减小复合膜的吸水率,提高复合膜的拉伸性能和热稳定性能.其中,NCC/RGO质量比为1∶1,NCC-RGO与PVA的质量比为1.0%的复合膜综合性能较好. |

| This study prepared nanocrystalline cellulose modified reduced graphene oxide (NCC-RGO).The NCC was attached onto the RGO surface through hydrogen bond.The NCC-RGO/PVA composite films were prepared by a solution mixing method.The structure and properties of the composite films were studied.The results showed that the NCC can prevent the RGO from aggregation.The NCC-RGO can be dispersed in water and the dispersion was stable.The properties of PVA were enhanced by NCC-RGO.The results showed that NCC can effectively prevent the aggregation of RGO,and NCC-RGO can be stably dispersed in water.As filler,NCC-RGO can reduce the water absorption of the composite films and improve the tensile properties and thermal stability of the composite films.Among them,the composite films with NCC/RGO mass ratio of 1∶1 and NCC-RGO and PVA mass ratio of 1.0% have good performance. |
