开发了一种热引发化学反应，以在晶圆级上对 CVD 生长的石墨烯进行功能化，并且该反应普遍扩展到碳纳米管和其他可以热转化为活性自由基的前体。当温度高于反应物的分解温度时，化学反应可以在没有氧气和水蒸气的情况下发生。由于表面掺杂和不均匀性，化学反应也被发现依赖于底物。结合微流控技术展示了大尺寸石墨烯图案。这种热引发的固相化学反应提供了一种简便且环保的方法来用各种官能团对碳纳米材料进行功能化。
A heat-initiated chemical reaction was developed to functionalize CVD-grown graphene at wafer scale and the reaction was universally extended to carbon nanotubes and other precursors that could be thermally converted to active radicals. The chemical reaction can occur in absence of oxygen and water vapor when the temperature is above the decomposition temperature of the reactants. The chemical reaction was also found to be substrate-dependent due to surface doping and inhomogeneity. A large-scale graphene pattern was demonstrated by combing with microfluidic technique. This heat-initiated solid-phase chemical reaction provides a facile and environmentally friendly approach to functionalize carbon nanomaterials with various functional groups.
