COATED SUBSTRATES HAVING UNDERCOATING LAYERS THAT EXHIBIT IMPROVED PHOTOCATALYTIC ACTIVITY
摘要
A coated substrate is disclosed. The coated substrate includes a substrate; an undercoating layer comprising at least one layer selected from a mixture of silica and zirconia; a mixture of silica and alumina; or a mixture of silica, alumina and titania overlaying at least a portion of the substrate; and a functional coating overlaying at least a portion of the undercoating. The coated substrates of the invention exhibit improved properties such as increased durability, photocatalytic activity, etc. as a result of the undercoating layer.
