ABSTRACT:
An acrylic or other polymer composition, optionally containing aluminum trihydrate, and having undoped and/or doped titanium dioxide dispersed evenly throughout is disclosed. Said composition provides a sterile surface which can be renewed. Said composition provides a highly sterile surface upon photoactivation of the surface by at least either low-level ultraviolet irradiation or ambient
atural light (as when using doped titanium dioxide). A method of using such a surface material is also disclosed. Said acrylic or other polymer composition may be adhered onto a polycarbonate or other polymeric backing, optionally by an intervening layer of a third polymer. The resulting acrylic or other polymer/polycarbonate or other polymer combination is adapted to provide ambient lighting when exposed to a light source.
