Dyes, fabric, pollution effect

Materials The damage that air pollutants can do to some materials is well known ozone in photochemical smog cracks rubber, weakens fabrics, and fades dyes hydrogen sulfide tarnishes silver smoke dirties laundry acid aerosols ruin nylon hose. Among the most important effects are discoloration, corrosion, the soiling of goods, and impairment of visibility. 

For molecular filtration, Chen et al. [80] fabricated carbonaceous nanoflbrous (CNF) membranes functionalized by beta-cyclodextrins (CNF- -CD membrane). The membrane showed a remarkable capability to function as an ideal molecular Alter through complexation of phenolphthalein molecules with the CD molecules grafted on the CNFs. As a typical dye pollutant, fuchsin acid could also be effectively removed from the solution through such a membrane. Engineering the surface of this CNF membrane may be used for other applications such as chiral separation and drug delivery.
