Abstract: A method for preparing a titanium oxide thin film is provide to allow uniform deposition of a high-quality thin film free from impurities on a large area, and to perform the deposition at a low temperature. The titanium oxide thin film is obtained by depositing a photocatalyst substance onto a top surface of an object to be deposited via any one process selected from the group consisting of APCVD, LPCVD, and PECVD. The photocatalyst substance is formed from a starting material including an organic titanium compound such as titanium tetraisopropoxide. The titanium oxide thin film is prepared by the method comprising the steps of: mounting an object to be deposited in a vacuum chamber; supplying a gaseous mixture containing an organic titanium compound including a material capable of forming a photocatalyst film, a carrier gas and an oxidant gas to the vacuum chamber; and forming a thin film on the surface of the object via plasma reaction of the gaseous mixture.

Abstract: 본 발명은 저온플라즈마 중합법을 이용하여 지지체 표면에 아민기를 함유한 유기 고분자를 균일하게 코팅함으로서, 한 단계(one-step)만으로 아민이 고정된 불균일계 염기 촉매를 제조하는 새로운 기술이다.
상세하게는, 저온플라즈마 중합법은 고체 표면 개질에 적합한 기술로, 코팅된 박막과 지지체 간의 접착력이 우수하며 건식방법으로 제조하기 때문에 용매에 의한 환경오염이 없고 경제적으로 지지체 표면을 개질할 수 있는 방법이다. 따라서 본 발명에서 제조된 아민 고정화 염기 촉매는 지지체 표면에 염기물질이 균일하고 안정적으로 부착될 수 있으며, 한 단계 만으로 촉매를 제조할 수 있어 많은 시간과 비용이 절약되는 장점이 있다.

Abstract: A method of forming a silver ion coating layer is provided to apply silver ions to an orthodontic device or to the surface of an implant, and to prevent the pathogenic oral microflora attachment that causes tooth-decay. A silver ion coating layer is formed by polymerization. To this end, a target part(35) fixed to a stabilizer is injected between both electrodes(31) inside a vacuum chamber(30), and a vacuum pump(20) is operated to make the chamber vacuum. The pressure in the chamber is measured by a pressure gauge(40). Under the vacuum condition, Ar or inert gas(60) is injected to clean the surface of a substrate. Acrylic acid gas(65) is introduced into the chamber as a monomer gas, and discharged with a generator(50). The discharge takes place in two steps, 80W for 4-6min and 30-40W for 15-25min. A resulting acrylic acid polymerization coating layer with a carboxylic group is immersed in a silver ion-containing solution for about 30minutes to substitute hydrogen ions with silver ions.
