Researchers at Cornell University in the U.S. have developed a technique that allows the creation of functional textiles that could be capable of filtering pollutants out of water and air.
By infusing cotton with a beta-cyclodextrin (BCD) polymer, the fabric can act as a filtration device.
The cotton fibers were scanned under an electron microscope and found to be unchanged after the process. When tested for the absorption of pollutants in water and air, the fibers showed greater uptakes than that of untreated cotton fabric or commercial absorbents.
The absorption potential of the technique could extend to other materials. There is a patent pending.
