摘要:
选用硅烷偶联剂KH560改性石墨烯，通过原位聚合法制备石墨烯/PET。用TEM对表面改性前后的石墨烯进行表征，并用FTIR、TG、DSC和特性黏度测试对石墨烯/PET的结构、热稳定性及结晶性能等进行研究。结果表明：石墨烯经硅烷偶联剂处理后分散效果较好；在实验范围内，原位聚合制备的石墨烯/PET中未检测到石墨烯与PET分子之间的化学结合键；石墨烯的加入使PET的DSC曲线发生了明显的变化，结晶曲线中出现了细而窄的结晶峰，熔融曲线中出现了明显的熔融双峰；石墨烯的加入提高了PET的热稳定性、结晶温度和结晶速率；当石墨烯含量为0.075 wt%时，石墨烯/PET比纯PET的结晶峰顶温度Tp提高了34.20 ℃，过冷度ΔT降低了29.37 ℃。
