| 摘 要： | 利用溶液涂覆成膜工艺在涂膜机上制得层叠状功能化石墨烯纳米带（SF-GNRs）/热塑性聚氨酯（TPU）复合材料薄膜。采用FTIR、XRD、XPS、TEM和FE-SEM对SF-GNRs的结构进行表征，并结合复合材料薄膜的氧气透过率、体积电阻率测试及表面形貌观察，研究了不同质量分数的SF-GNRs对TPU复合材料薄膜阻隔和抗静电性能的影响。结果表明:所得高比表面积SF-GNRs在TPU基体中分散良好；当SF-GNRs质量分数为1.0%时，SF-GNRs/TPU复合材料薄膜的氧气透过率相比纯TPU薄膜降低了67.76%，阻隔性能得到明显改善；当SF-GNRs质量分数达到1.0%～1.5%时，SF-GNRs/TPU复合材料薄膜出现了电渗流行为，表现出优良的室温导电性能。

| Abstract: | The stack-like functionalized graphene nanoribbons (SF-GNRs)/thermoplastic polyurethane (TPU) composite films were obtained by solution coating film method on a coating machine.FTIR,XRD,XPS,TEM and FE-SEM were used to characterize the structure of SF-GNRs.Meanwhile,by means of oxygen transmission rate, volume resistivity test,and the observation of surface morphology,we studied the effect of SF-GNRs with different mass fractions on the barrier and antistatic properties of TPU composite films.The results show that the SF-GNRs with high surface area are evenly dispersed within TPU matrix.As a result,when the mass fraction of SF-GNRs is 1.0%,the oxygen transmission rate of SF-GNRs/TPU composite films reduces by 67.76%,compared with that of the neat TPU film.Barrier property has obvious improvement.In addition,as SF-GNRs mass fraction reaches to 1.0%-1.5%,SF-GNRs/TPU composite films appear electrical percolation behavior which exhibit the excellent room temperature conductivity. |
