Abstract
An acrylic or other polymer composition, optionally containing aluminum trihydrate, and having undoped or doped titanium dioxide dispersed throughout is disclosed. Said composition provides a “renewable” surface and further provides a highly-sterile surface upon photoactivation of the surface by at least either low-level ultraviolet irradiation or ambient/natural light (as when using doped titanium dioxide).
Claims19
A surface material comprising
- a polymer having dispersed throughout an effective amount of TiO2 and/or doped TiO2 to result in at least the surface of said surface material becoming at least 99% sterile upon exposure to at least one of the following:
- ambient, natural, or ultraviolet light conditions.
A method of creating and maintaining a sterilizable environment from an environment comprising a) surfacing said environment with a surface material having dispersed throughout a compound which reacts in the presence of ambient, natural, or ultraviolet light to sterilize the surface of said surface material such that exposure results in at least the surface becoming at least 99% sterile;
- and b) renewing the surface of said surface material when said surface material is damaged.
