采用简单的溶液混合-蒸发法制备了一种未见报道的纳米复合（CMC/GO）高性能薄膜。通过广角X射线衍射、傅里叶变换红外光谱、拉曼光谱、扫描电子显微镜、热重分析和力学性能测试研究了复合膜的结构、热稳定性和力学性能。从这些不同的研究中获得的结果表明，CMC和氧化石墨烯能够形成均匀的混合物。与纯CMC相比，石墨烯基材料的拉伸强度和杨氏模量在掺入1wt%氧化石墨烯后分别显著提高67 ± 6%和148 ± 5%。此外，DMA复合膜还显示出高达250 °C的高储能模量。
A previously unreported nanocomposite (CMC/GO) high-performance film was prepared by a simple solution mixing-evaporation method. The structure, thermal stability, and mechanical properties of the composite films were investigated by wide-angle X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, thermogravimetry analysis, and mechanical testing. The results obtained from these different studies revealed that CMC and graphene oxide were able to form a homogeneous mixture. Compared with pure CMC, the tensile strength and Young’s modulus of the graphene-based materials were improved significantly upon incorporation of 1 wt% graphene oxide by 67 ± 6 % and 148 ± 5 %, respectively. In addition, the DMA composite films also showed a high storage modulus up to 250 °C.
