Abstract

Polycarbonate diol (PCD), isophorone diisocyanate (IPDI)와 dimethylol propionic acid (DMPA)를 출발물질로 하여 수분산 폴리우레탄(waterborne polyurethane dispersion, WPUD)을 합성하였다. WPUD에 아크릴 단량체인 methyl methacrylate (MMA)를 첨가하여 수분산 아크릴 폴리우레탄 (waterborne acrylic polyurethane dispersion, AUD)을 합성하였다. 이 AUD와 물에 분산되어 있는 multi-walled carbon nanotube (MWCNT)를 혼합하여 전도성 코팅 용액을 제조한 후 polycarbonate 시트 위에 도포하여 코팅 도막을 형성하였다. AUD 중의 MMA의 첨가량이 증가될수록 코팅도막의 연필경도, 내마모성 및 내약품성은 향상되었으나 전기 전도도는 감소하였다. 반면에 전도성 코팅 용액 중의_x000D_ MWCNT의 첨가량이 증가될수록 코팅 도막의 연필경도, 내마모성 및 내약품성은 감소되었으나 전기 전도도는 증가하였다.

Waterborne polyurethane dispersion (WPUD) was synthesized from polycarbonate diol (PCD), isophorone diisocyanate (IPDI) and dimethylol propionic acid (DMPA) as starting materials. Then, waterborne acrylic polyurethane dispersion (AUD) was synthesized by reacting the WPUD with an acrylate monomer, methyl methacrylate (MMA). Subsequently, the AUD was mixed with multi-walled carbon nanotube (MWCNT) to yield a conductive coating solution, and the mixture was coated on the polycarbonate substrate. With increasing the amount of MMA in the AUD, the pencil hardness, abrasion resistance and chemical resistance of the coating films were improved, but the electrical conductivity of the coating films was decreased. On the other hand, the pencil hardness, abrasion resistance and chemical resistance of coating films were decreased, but the electrical conductivity was enhanced with increasing the amount of MWCNT in the conductive coating solutions.
