We suggest a new method to evaluate the anti-smudge performance of LCD panels. The anti-smudge performance is characterized by oleic acid contact angle. This method shows accurate and reproducible result and overcomes the difficulty of quantitative evaluation for the anti-smudge characteristic and low reliability in several proposed measurements.

Herein, resin-formed polysilsesquioxanes (PSSQs) were synthesized using monomolecular fluoro silane as a precursor. The synthesized PSSQs exhibited anti-smudge performance and were used as coating liquid. Two structures were acquired by controlling the amount of the silane precursor and the K₂CO₃ catalyst; these materials were used to prepare the anti-smudge coating liquid solution. The synthesized product was analyzed by various methods such as nuclear magnetic resonance spectroscopy, X-ray diffraction analysis, gel permeation chromatography, and water contact angle measurement. The results confirmed that the as-synthesized PSSQs exhibited the ladder structure and had a molecular weight of 5,117 g/mol and water contact angle of 102.31°.

과불소 에테르 화합물(PFPE)은 높은 접촉각 및 낮은 표면에너지, 우수한 윤활제 성질과 방오성의 특성을 가지고 있어 산업적으로 많은 관심을 받아왔다. 반면에, 합성단계의 복잡성과 위험성을 갖고 있어 많은 연구가 되어 오지 못했다. 본 연구에서는 과불소 폴리에테르 올리고머 형태의 새로운 실란화합물을 합성하고 $^{19}F$-NMR 및 $^1H$-NMR을 통하여 구조분석 하였다. 또한 코팅필름의 접촉각 및 흐름각, 내오염성 등 표면 특성을 조사하였다. 그 결과, 기존의 방오성 필름보다 낮은 흐름각과 우수한 내오염성의 특징을 보여 방오성 필름 코팅 제로서 산업적 가능성을 확인하였다.
