| 目的 以纳米纤维素为基材，氧化石墨烯作为增强相，制备氧化石墨烯/纳米纤维素复合薄膜。方法 分别采用酸碱直接处理法和酸碱交替处理法制备纳米纤维素，采用一步氧化法和循环氧化膨胀法制备氧化石墨烯，观测其形貌，得出最佳制备工艺。测试由最优工艺制备的纯纤维素薄膜和复合薄膜的拉伸和润湿性能。结果 酸碱交替处理法制备的纳米纤维素薄膜表面结构清晰，且纤维直径可达50 nm，循环氧化-膨胀法制备的氧化石墨烯片层厚度在纳米级别。当纳米纤维素与氧化石墨烯的质量比为20:1时，氧化石墨烯/纳米纤维素复合薄膜的拉伸强度达149.68 MPa，与纯纤维素薄膜相比增加了19.55%，且复合薄膜的接触角大于纯纤维素薄膜。结论 证实了氧化石墨烯能够增强纳米纤维素薄膜，在一定程度上说明氧化石墨烯/纤维素复合薄膜对水分子的阻隔性优于纤维素薄膜。 |

| Objective In order to combine the advantages of nano cellulose and graphene, in this paper, we used nanocellulose as matrix, and graphene oxide as reinforcing phase, fabricate the graphene oxide/nano cellulose composite film. Method The cellulose nanofibrils made by acid and alkali direct treatment method and acid and alkali alternate treatment. The graphene oxide made by one step oxidation method and cycle oxidation-expansion method. Then observed its morphology, found the best preparation process. Tested the tensile strength and wetting property of graphene oxide/ nano cellulose composite film, which made by the optimum process. Results The results showed that acid and alkali alternate treatment can obtain nano cellulose film which had clear structure, and the diameter of fibre was 50 nm. Cycle oxidation-expansion method can made graphene oxide with thin thickness at the nanoscale. When nanofiber and graphene oxide’s quality ratio was 20:1, the tensile strength of GO/nano cellulose conposite film could reach 149.68 MPa, compared with the pure cellulose film, whch increased 19.55%. and the contact angle of composite film is greater than the pure cellulose film. Conclusion It was confirmed that the graphene oxide can enhance nano cellulose film, to a certain extent, the barrier property of the composit film to water was superior to cellulose film. |
