The BCNs were chemically modified using acetic anhydride with the aim of improving its dispersion and interfacial adhesion. Acetylation of BCNs was confirmed by FT-IR spectroscopy. Morphology studies using TEM and SEM revealed that a reasonable dispersion of the modified BCNs in the EVA matrix was accomplished. The DSC data displayed a little shift in the T to higher temperatures with the incorporation of both modified and unmodified BCNs. Increased thermal stability of the nanocomposites consisting acetylated BCNs was confirmed by TGA technique. DMA measurements highlighted that the storage modulus increased and the damping properties decreased for the nanocomposites with regard to the neat EVA.
BCNs 用乙酸酐进行了化学修饰，目的是改善其分散性和界面附着力。FT-IR 光谱证实了 BCNs 的乙酰化。TEM 和 SEM 的形貌研究表明，成功地实现了改性 BCNs 在 EVA 基体中的合理分散。DSC 数据显示，随着改性和未改性 BCNs 的加入，T 向较高温度略有移动。TGA 技术证实，含有乙酰化 BCNs 的纳米复合材料的热稳定性提高。DMA 测量结果表明，与纯 EVA 相比，纳米复合材料的储能模量增加，阻尼性能降低。
