Abstract

In this study, Cu nanoparticles encapsulated by a few layers of graphene shells (designated as Cu@FLG) were synthesized through a facile pyrolysis process involving CuO and liquid oligoacrylonitrile (LANO). The resulting Cu@FLG composite not only demonstrates excellent electrical conductivity but also exhibits ultrahigh stability against oxidation and corrosion, even when exposed to high temperatures or nitric acid solutions. The remarkable stability is attributed to the compact encapsulation by few layers of graphene shells. The unique Cu@FLG composite shows great potential for applications in the electronic industry due to its low cost, high yield, and exceptional electrical and chemical stability.

具有优异导电性和化学稳定性的Cu@Few-Layer石墨烯壳复合材料的合成与研究

在本研究中，通过CuO和液态低聚丙烯腈（LANO）的简单热解过程，合成了由几层石墨烯壳包裹的Cu纳米颗粒（指定为Cu@FLG）。由此产生的Cu@FLG复合材料不仅具有优异的导电性，而且具有超高的抗氧化和抗腐蚀稳定性，即使暴露在高温或硝酸溶液中也是如此。这种显著的稳定性归功于石墨烯壳层的紧凑封装。独特的Cu@FLG复合材料由于其低成本，高产量和卓越的电气和化学稳定性，在电子工业中显示出巨大的应用潜力。
