-- Multifunctional Cu-TiO2-PU having both photocatalyst and adsorbent activity and manufacturing method thereof

摘要

The present invention multi-functional copper having both the function of the photocatalyst and the adsorbent-relates to a titanium dioxide / polyurethanes and their preparation, and more particularly, the titanium dioxide thin film is fixed to the polyurethane substrate of a porous honeycomb structure, the titanium dioxide It characterized in that the copper (Cu) is doped in the thin film, multi-copper-relates to a titanium dioxide / polyurethanes and their preparation. The multi-function copper according to the invention to the titanium dioxide / polyurethane is used as the adsorbent is possible to use the porous polyurethane as the support, it can be chemically bonded by the titanium dioxide and the electronic properties will not be peeled off the titanium dioxide thin film easily, copper doped by exhibits a superior photocatalytic activity even including ultraviolet rays by lowering the band gap energy of the titanium dioxide visible light region, can be activated even weak visible light of a fluorescent lighting or a lamp, etc., energy is prior art compared to the use as a photocatalyst for It is less economical to use. In addition, copper-doped when the light by the use of vapor deposition without affecting the doping process to the bond between the titanium dioxide and polyurethane, it is possible to enable mass production is possible and reproduction used semi-permanently, in place of the conventional adsorbents and photocatalytic room air It can be helpful for purification. ;
