以正己烷（C6 H14）和乙醇（C2 H5 OH）为碳源，采用电弧放电法制备了规则和缺陷洋葱状碳（OLC）纳米粒子。OLC纳米颗粒中缺陷位点的形成归因于乙醇中氧的引入。结果表明，高真空或采用无氧原料有利于形成规则的洋葱状组织。对于有缺陷的OLC/石蜡复合材料，有价值的微波吸收面积（
Both regular and defective onion-like carbon (OLC) nanoparticles were prepared by the arc-discharge process using hexane (C6H14) and ethanol (C2H5OH) as carbon sources. The formation of defective sites in OLC nanoparticles is ascribed to the introduction of oxygen of ethanol. It is shown that high vacuum or using raw materials without oxygen is favorable to form regular onion-like microstructure. For defective OLC/paraffin composites, the valuable microwave-absorption areas (
