类玻璃炭孔隙结构的TEM考察 丁志明1,张营煌2,柯泽豪2,胡宪霖2 (1.成功大学材料科学与工程系,台湾,台南;2.逢甲大学材料科学与工程系,台湾,台中) 摘要:主要探讨酚醛树脂为前驱物的类玻璃炭,在炭化及石墨化至2 400 ℃过程中,利用透射电子显微镜观察其微结构的变化.发现一些明显的微晶碳层平面完好地堆栈在孔洞周围,这些碳层结晶尺寸在20 nm~200 nm之间.同时,这些碳层平面排列十分整齐并延伸至孔洞的表面,这些排列完好的碳层平面主要是因在小分子物气化过程中所产生.这个气化反应会生成像石墨化应力的效果,导致在孔洞内部及边缘形成高结晶碳层平面. 关键词:电子显微镜; 孔隙率; 微结构; 类玻璃碳; 炭化; Electron microscopy; Porosity; Microstructure; Glass-like carbon; Carbonization......
