A paper on the research undertaken by the institute based in Shenyang, capital of north China’s Liaoning Province, was published in the latest issue of the international journal Advanced Materials Interfaces.
Liu said that industrial sewage contains various oils and organic components that becomes ecologically hazardous once mixed with water.
The new material provides a low-cost industrial sewage treatment solution, she added.
Liu said that the base material of the polyurethane sponge is cost-effective.
Only the small amount of graphene, in the coating, is expensive. However, with the increase in production of graphene in China, the price would gradually come down she added.
