Xinjiang Institute of Physics and Chemistry, Chinese Academy of Sciences developed super hydrophilic cotton fabric

Recently, technicians from the Xinjiang Institute of Physics and Chemistry of the Chinese Academy of Sciences have made a series of new developments in the field of functional cotton fabric research.

It has been found that responsive cotton fabric is used as the membrane material. The filtration method can directly realize the efficient and rapid separation of the crude oil mixture. The oil content in the mixture has little effect on the filtrate flux during the separation process. The material can be used in the oilfield production fluid. Oil and water separation process. On the basis of this research, the researchers conducted an in-depth study on the local cotton fiber in Xinjiang. By finely regulating the surface morphology and functional groups of the single cotton fiber, the material has a biomimetic structure similar to the fish skin and imparts super hydrophilicity. performance.

Meanwhile, the difference for the antibacterial properties of cotton fabric, UV light and easy degradation problems, researchers have incorporated a polymer nanocomposite cotton fabric surface by spray coating, the treated fabric inhibition rate of more than 99% of E. coli. In addition, the cotton fabric also has the multi-functional properties of enhanced mechanical properties, hydrophobicity, and lipophilicity. Cotton fabrics have a UV resistance of nearly 100% and an ultraviolet protection factor of over 40, meeting the national standards for textile UV protection.

It is reported that the above research work has been supported by the National “Thousand Talents Program” and the Fine Chemicals Industrialization Alliance of the Chinese Academy of Sciences. Some materials have been mass-produced or have recently received commercial orders.
