采用氧化法将碳纳米管纵向切割成氧化石墨烯纳米带，利用溶液成形在涂膜机上制备氧化石墨烯纳米带/TPU 复合材料薄膜。 FT-IR、拉曼光谱、XRD、FE-SEM、TEM等测试表明，碳纳米管成功地被纵向切割成带状结构的氧化石墨烯纳米带。力学测试表明，当氧化石墨烯纳米带用量为2％(质量分数)时，复合材料薄膜弹性模量与拉伸强度相比 TPU 薄膜提高了160％与123％。氧气透过率测试表明当氧化石墨烯纳米带用量为2％(质量分数)时，复合材料薄膜氧气透过率降低77％，阻隔性能明显提高。
The graphene oxide nanoribbons were prepared by oxidation longitudinal cutting carbon nanotubes, and the graphene oxide nanoribbons/thermoplastic polyurethane composite films were fabricated by solution on the coating machine.FT-IR,Raman,XRD,FE-SEM,TEM results showed that the carbon nanotubes had been successfully cut into graphene oxide nanoribbons of banded structure.Mechanical properties showed that when the content of graphene oxide nanoribbons was 2wt%,the elastic modulus and tensile strength of composite film increased by 160% and 123%,compared with the pure TPU film.The oxygen transmission rate of TPU film declined by about 77% at low graphene oxide nanoribbons loading of 2.0wt%,and the barrier properties has improved significantly.
