Twisted carbon fiber (TCF) aerogel with good selective sorption is produced in large scale by using raw cotton as the precursor. TCF aerogel shows highly efficient sorption of organic liquids (pump oil: up to 192 times its own weight; chloroform: up to 115 times its own weight). Moreover, it could be regenerated many times without decrease of sorption capacity by distillation, combustion or squeezing, which depends on the type of pollutants.
采用棉花作为前驱体制备出具有良好选择吸附性能的扭曲碳纤维（TCF）气凝胶。TCF 气凝胶对有机液体（油泵油：高达自身重量的 192 倍；氯仿：高达自身重量的 115 倍）具有高效的吸附作用。此外，它可以通过蒸馏、燃烧或挤压进行多次再生，而不会降低吸附能力，具体取决于污染物的类型。
