  • 본 논문은 게이트 절연막에 OTS(n-octadecy trichlorosilance) 혼합용액을 이용하여 SAMs(Self-Assembled Monolayers)막을 형성하였다. OTS 혼합용액은 OTS를 0.1w%와 0.5w% 각각을 클로로포름 30w%와 헥산 70w%에 혼합하여 만들었다. 이 혼합용액을 게이트 절연막위에 표면처리하였다. 활성층인 Pentacene이 게이트 절연막 위에 증착될 때, OTS 혼합용액의 비에 따라 누설전류특성을 보았다. OTS를 0.1w% 처리한것이 0.5w%보다 누설전류가 더 작게 나타났다. 결과적으로 OTFT의 게이트 절연막의 절열특성은 향상시키는데 OTS 혼합용액의 비가 큰 영향을 준다.

  • This work reports a facile and effective antibacterial coating for oxide substrates. As a coating material, a random copolymer, abbreviated as poly(TMSMA-r-PEGMA), was synthesized by radical polymerization of 3-(trimethoxysilyl)propyl methacrylate (TMSMA) and poly(ethylene glycol) methyl ether methacrylate (PEGMA). Polymeric self-assembled monolayers of poly(TMSMA-r-PEGMA) were formed on various inorganic oxide substrates, including silicon oxide, titanium dioxide, aluminum oxide, and glass, via the simple dip-coating process. The polymer-coated substrates were characterized by ellipsometry, contact angle measurements, and X-ray photoelectron spectroscopy. The bacterial adhesion on the polymer-coated substrates was completely suppressed compared to that on the uncoated substrates.
