Abstract

Hydrophobic films are widely used in aerospace, military weapons, high-rise building exterior glass, and non-destructive pipeline transportation due to their antifouling and self-cleaning properties. This paper details the successful preparation of hydrophobic epoxy caged sesquioxane (EP-POSS) via two steps of simple organic synthesis, along with studies on the effects of viscosity and reaction time on the reaction. Interestingly, the EP-POSS presented a large contact angle of 125°, indicating its excellent hydrophobicity. The surface micromorphology was observed via FE-SEM (field emission scanning electron microscopy), transmission electron microscopy (TEM), and atomic force microscopy (AFM), and the structural composition and elemental contents were analyzed via X-ray photoelectron spectroscopy (XPS) and energy-dispersive spectrometry (EDS). Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) tests showed that EP-POSS had excellent thermal properties, and the first degradation reaction occurred at 354 °C. The mechanical performance and abrasion resistance results demonstrated that EP-POSS could be used in solar panels.

摘要

疏水薄膜因其防污和自清洁特性而广泛应用于航空航天、军事武器、高层建筑外墙玻璃及无损管道运输等领域。本文详细介绍了通过两步简单有机合成成功制备疏水环氧笼型倍半硅氧烷（EP-POSS）的过程，以及对粘度和反应时间对反应影响的研究。有趣的是，EP-POSS呈现出125°的大接触角，表明其具有优异的疏水性。通过场发射扫描电子显微镜（FE-SEM）、透射电子显微镜（TEM）和原子力显微镜（AFM）观察表面微观形态，并通过X射线光电子能谱（XPS）和能量色散光谱（EDS）分析结构组成和元素含量。热重分析（TGA）和差示扫描量热法（DSC）测试表明，EP-POSS具有优异的热性能，首次降解反应发生在354℃。力学性能和耐磨性能结果表明，EP-POSS可用于太阳能电池板。
