This design is for door handles (door doors, interior doors, glass doors, toilet doors, etc.). The door handles used at home as well as in large buildings are used by various people to share various invisible substances, odors, E. coli bacteria and bacteria that cause diseases are contaminated, and there is a problem in hygiene. To solve these problems, a more hygienic door handle is formed. The present invention dissolves and disperses titanium dioxide in water and alcohol in the door handle. • If the configured oxygen catalyst solution was 23 times the fine spray coating is kind of polymer thin film on the door handle surface polymer film reacts with oxygen, hydroxyl radical (OH -) and superoxide ion (O 2-) hydroxyl radicals in the generation (OH -) and superoxide ion (O 2-) which is contaminated with harmful substances door handle by the strong oxidative action of the Oxygen antibacterial door handle consisting of more hygienic door handles by removing birds, Escherichia coli, bacteria, bacteria, etc. The oxygen catalyst solution used in this design is harmless to human body and unlike light catalysts, it does not require light and It reacts with oxygen for 24 hours and shows the effect of oxygen catalyst, and it removes all kinds of harmful substances, odors, E. coli, bacteria, and bacteria that are contaminated by door handle by strong oxidation, and also has excellent washing resistance and abrasion resistance. Efficacy was shown to be able to construct a more hygienic door handle.Door handle, oxygen catalyst effect, titanium dioxide phosphate.본 고안은 문손잡이 (현관문, 실내문, 유리문, 화장실문 등)에 있어 가정에서는 물론 큰 건물내에서 사용하는 문손잡이는 여러 사람들이 공동으로 사용함으로 인하여 눈에 보이지 않는 각종 유해물질이나 냄새, 질병을 유발시키는 대장균 박테리아, 세균 등이 오염되어 위생에 문제가 있는데 이런 문제점을 해결하여 보다 위생적인 문손잡이를 구성하는 것이 목적인바 본 고안은 문손잡이에 인산이산화티타늄을 물이나 알코올에 용해 분산시켜서 구성한 산소촉매 용액을 2～3회 미세분사 코팅하면 문손잡이 표면에 폴리머 박막이 생기는데 폴리머 박막은 산소와 반응하여 히드록실 라디칼(OH-)과 슈퍼 옥사이드 이온(O2-)이 발생하는데 히드록실 라디칼(OH-)과 슈퍼 옥사이드 이온(O2-)의 강한 산화작용에 의해서 문손잡이에 오염되는 각종 유해물질과 냄새, 대장균, 박테리아, 세균
