Silane Coupling제로 표면 처리된 ATO 나노입자를 이용하여 제조된 대전방지 ATO/EPOXY 복합체의 코팅 물성

Abstract

For purpose of anti-static film remaining unchanged in the condition of 160℃, organic solvent, acid and base solution 0.01∼0.03 m particles of Sb doped tin oxide(ATO) were grafted by 3-Glycidyloxypropyltrimethoxysilane(GPTS) for improving interfere bonding force between ATO and epoxy resin. The particles were dispersed in 2-methoxyethanol with YD-128(Bisphenol A type epoxy resin, Kukdo chemical) and 1-imidazole as hardener. The anti-static solutions were coated on PI film as thickness of 0.1 m. Surface resistivity of anti-static film containing conductive polymer became 10¹² Ω/ after 32 hours in 160 ℃. The surface resistivity of ATO grafted by GPTS / Epoxy coating layer remained as 107.6 Ω/ in 160 ℃ for 7 days. ATO grafted by GPTS / Epoxy coating layer coated on PI film was dipped in acetone for 7 days. The surface resistivity remained unchanged as 107.6 Ω/. The anti-static layer dipped in water solutions containing each KOH 10 wt % and H₂SO₄2 wt% was ultra-sonicated for 10 minutes per once until 30th. The surface resistance of anti-static layer containing ATO grafted by GPTS remained unchanged.
