Abstract A wet ball milling route was used to synthesise SiC-graphene core-shell nanoparticles in situ from graphite and SiC nanoparticles. Graphite flakes were gradually exfoliated into fresh graphene nanosheets (GNSs) without significant defects, which is attributed to mechanical shearing and moderate impaction forces between graphite flakes, milling balls and SiC nanoparticles during the wet milling. The non-destructive exfoliation is characterised by Raman, Fourier transform infrared and X-Ray photoelectron spectroscopies. The freshly produced GNSs are energetically unstable and thin enough to be flexible and this drives the in situ attaching and scrolling of GNSs on the SiC nanoparticles. The SiC nanoparticles and GNSs are well dispersed in the wet medium and the SiC nanoparticles are individually wrapped. It has been estimated that > 50% of the produced GNSs are wrapped around the SiC nanoparticles and these GNSs are generally ≤ 6 layers.

使用湿球磨法原位合成 SiC-石墨烯核壳纳米粒子

摘要 采用湿式球磨路线，以石墨和碳化硅纳米粒子为原料，原位合成碳化硅-石墨烯核壳纳米粒子。石墨片逐渐剥离成没有明显缺陷的新鲜石墨烯纳米片（GNS），这归因于湿磨过程中石墨片、研磨球和 SiC 纳米颗粒之间的机械剪切和适度的冲击力。非破坏性剥离的特点是拉曼、傅里叶变换红外和 X 射线光电子光谱。新生产的 GNS 在能量上不稳定且足够薄以具有柔韧性，这驱动了 GNS 在 SiC 纳米颗粒上的原位附着和滚动。SiC 纳米颗粒和 GNSs 很好地分散在湿介质中，并且 SiC 纳米颗粒被单独包裹。据估计 >
