在静态气氛下对不同塑料废弃物热解得到的碳烟进行了表征，结果表明，在热解过程中形成了60±10nm的碳洋葱。已经进行了各种物理化学研究，以探索碳洋葱的表面和本体性质。加热室的容积对碳洋葱的生成和沉积起着至关重要的作用。聚丙烯、聚乙烯（高密度和低密度）和聚丙烯酸酯等塑料废弃物的热解完全形成碳洋葱，而聚对苯二甲酸乙二醇酯、聚氯乙烯和聚苯乙烯的热解则得到带有碳洋葱的结晶炭渣。
The characterization of carbonous soot obtained from the pyrolysis of different plastic wastes under static atmosphere showed the formation of carbon onions of 60±10nm. Various physico-chemical studies have been carried out to explore the surface as well as bulk properties of carbon onions. The volume of heating chamber plays a crucial role on production and deposition of carbon onions. The pyrolysis of plastic wastes such as polypropylene, polyethylene (high and low density) and polyacrylate completely resulted into the carbon onions, whereas crystalline carbon residue with carbon onions was obtained with the pyrolysis of polyethylene terephthalate, polyvinyl chloride and polystyrene.
