Tetraethyl orthosilicate (TEOS) 혹은 1,2-bis(triethyoxysilyl)ethane (BTSE)과 여러 종류의 organosilane들을 공중합하여 유 무기 혼성 메조포러스 물질들을 제조하고, 이들이 공기 중의 휘발성 유기화합물(VOC)들을 흡착 제거하는 능력을, TEOS 만을 사용하여 제조한 친수성 무기 메조포러스물질인 SBA-15와 비교 평가하였다. 유기 구조의 도입에 의한 소수성의 증대는 메조포러스 물질이 VOC를 흡착 제거하는데 긍정적 효과를 줌을 관찰하였다. 특히 BTSE와 phenyl triethoxysilane을 중량비 90:10으로 공중합한 유 무기 혼성 메조포러스 물질의 VOC 제거 능력은 우수하였다. 또, 물속에 분산된 기름 성분을 흡착 제거하는데 유 무기 혼성 메조포러스 물질들을 유용하게 응용할 수 있음도 정성적으로 관찰하였다.

Inorganic-organic hybrid polymer provides various advantages including low-temperature process, high dielectric constant and direct photo-patterning. The hybrid dielectric was synthesized by the sol-gel process in which an acid-catalyzed solution of Si alkoxide and Zr alkoxide was used as a precursor. The electrical performance of transistors with hybrid dielectric was investigated.

Second-order nonlinear optical(NLO) materials have been extensively studied for applications in photonic devices, such as frequency doubling and electro-optical(EO) modulation, because of their large optical nonlinearity, excellent processibility, low dielectric constant, and high laser damage thresholds. The poling behaviour of NLO chromophore in organic/inorganic matrixes showed the randomization of poled NLO chromophore in the absence of poling Held. The liquid crystal molecules in a droplet showed a long-range orientational order along a director. Therefore, liquid crystal effects on poling behaviour of NLO chromophore dispersed in organically modified inorganic sol-gel materials were investigated. Using sol-gel process for the development of NLO material has received increasing attention, Organically modifked inorganic NLO sol-Eel materials are obtained via incorporation of the organic NLO active chromophore into an alkoxysilane based inorganic network. One of the most important thing in this works was that tetraethoxysilane(TEOS) and methyltrimathoxysilane(HTMS) were used as precursor followed by hydrolysis and condensation without using any acidic catalyst during the process. The NLO chromophores in the liquid crystal nanodomains were well mixed with I/O hybrid matrix, deposited on transparent ITO-coated glasses. The poling behaviour of liquid crystal effects of NLO chromophore dispersed in I/O hybrid matrix were investigated by UV-vis spectroscopy. Size distribution and morphology of the NLO chromophores doped in the liquid crystal nanodomains dispersed in I/O hybrid matrix were investigated by SEM.

In this study we performed test to compare and analyze the chloride diffusion properties in concrete according to organic coating materials used at concrete structures widely and inorganic coating materials as eco-materials in recently. The results of study were shown as follow ; 1) Chloride diffusion coefficient was low as low as and that of organic and inorganic painted was lower than non-painting 2) In case of inorganic coating material applied in this study, it should be possible to evaluate the chloride diffusion properties by CTH method. Because presumption value by CTH method is similar with real estimate value by digestion experiment.
