Abstract
Chitosan is a N-containing biopolymer that can form high-quality films on glass, quartz, metals and other hydrophilic surfaces. Pyrolysis of chitosan films under argon at 800 °C and under inert atmosphere gives rise to high-quality single layer N-doped graphene films (over 99% transmittance) as evidenced by XPS, Raman spectroscopy, and TEM imaging.
摘要
壳聚糖是一种含氮的生物聚合物，可在玻璃、石英、金属和其他亲水表面形成高质量的薄膜。在氩气和惰性气氛下，壳聚糖薄膜在 800°C 下热解会产生高质量的单层 N 掺杂石墨烯薄膜（透光率超过 99%），这一点可通过 XPS、拉曼光谱和 TEM 成像得到证明。
