  • This study is intended for the review of the standards related with the released contaminants from building materials used in the building room. Because currently being used industry standard and test method for the emissions of air pollutant are ambiguous so the new enactment and revision of the test methods and standards need to be addressed to match the actual situation in the construction industry. Based on actual evaluation for seveal sealants used in the job site, this study will present a direction for the revision and new enactment of standards and test method appropriately.

  • Recently, to ensure the high openness and prospect right of the building, curtain wall system is mainly applied to the high-rise buildings at domestic and overseas. As a result, the use of Structural Sealant is increasing. Structural Glazing Sealant is applied with the glass and AL-FRAME (Mullion) that the strong structural strength is required to hold. However, the structural sealant at the construction site in a variety of external influences, such as wind load, thermal load, uv, chemical pollutants etc, in case of storing condition, if structural sealant stored in high temperature for a long period time, it will not perform well compared with initial performance. In this study, the influence of the performance of one-component structural sealant evaluated for proper storage conditions at the construction site and how to use the non-intended.

  • Resin impregnation of carbon materials was affected by surface of carbon materials. The surface of carbon materials with coupling treatment improved comparability and wettability with resin, and that increased impregnation efficiency and properties of carbon materials. As a results of FT-IR, The silanol was coated on carbon surface with one layer. Coupling treatment of carbon materials increased impregnation efficiency, which improved porosity, mechanical strength, density and friction behavior.

  • Organo bifunctional silane (TESPD) is added into silica containing NR and its effects are investigated with respect to the vulcanization properties, the processability, and the physical properties. The addition of the TESPD into silica filled NR compound increases the degree of crosslinking by formation of a strong 3-dimensional network structure with silica surface via coupling reaction, which results in an improved mechanical property. It also improves the processabilities compared to the Control compound.

  • There are many elastomeric joint sealant applications in construction such as structural glazing, weatherproofing and insulating glass fabrication etc. Each sealant joints require unique durability functions to perform well through building life cycle. Elastomeric joints in bathroom and kitchen is one of areas which require durable sealing. In this application, anti fungal durability is proprietary function of sealant during building life cycle. Premature failure of anti fungus resistance of sealant is putting big stresses to general contractor as well as the inhabitants due to costly rework and poor sanitation. Accordingly, when chemists design a product, they must take into account various parameters not only formulation components also test conditions in order to have long term fungal durability. This paper reviews several biocide options with various industry standards for fungus resistance performance to suggest making new test method for construction sealant industry.

  • 3-아미노프로필기를 함유한 실리카 전구체를 물질 조성 성분, 유화제 및 촉매로 이용하여 다른 활성기를 가지는 3-머캅토프로필트리알콕시 실란, 비닐트리알콕시 실란 등과 반응시켜 여러 가지 크기의 구 입자를 제조하였다. 구는 이들 분자의 자기 조립에 의하여 형성되었으며 외부적으로 아무런 물리적, 화학적 자극을 가할 필요가 없었다. 생성되는 구의 크기는 반응 혼합물의 조성 즉 반응 혼합물에 들어 있는 3-아미노프로필기를 함유한 전구체의 양에 따라 결정되었다. 생성물에 들어 있는 3-아미노프로필기의 양은 최대 20 몰%를 넘지 않았으며, 얻어진 구의 지름은 반응물 조성에 따라 수십 nm에서 수 $\mum$에 달하였다.

  • 다결정 실리콘 (Poly-Si)은 LPCVD를 이용하여 $750^{\circ}C$에서 증착하였다. 증착된 실리콘 박막은 실란, 수소 및 헬륨 가스를 이용하여 증착하였다. 성장된 poly-Si의 특성은 Raman spectroscopy 및 SEM을 이용하여 분석하였다. 헬륨 가스의 양을 15 sccm으로 고정하고 실란과 수소의 가스비를 60:0에서 20:40까지 가변시켰다. 활성화 에너지는 전류-전압 측정을 통해 Arrhenius plot을 이용하여 계산하였다. 박막 트랜지스터는 quartz 기판 위에 제작되었다. 게이트 절연막으로 TEOS $SiO_2$를 이용하였으며 source 및 drain 전극으로 Al을 이용하였다. 이 때 제작된 박막 트랜지스터의 전류 점멸비, 전계 효과 이동도, SS 및 문턱 전압은 각각 $10^5$, $76\;cm^2/V-s$, 167 mV/decade 및 1.43 V이었다.
