Physical Properties of Hydrophobic Epoxy-Based Silsesquioxane (EP-POSS) Photovoltaic Materials

With the increasing application of photovoltaic panels in the field of power generation, hydrophobic materials have gradually received attention from researchers. Because EP-POSS (epoxy-based silsesquioxane) has many excellent properties, such as transparency, hydrophobicity, flame retardancy and weather resistance, it may be widely used in photovoltaic power generation boards in the future. Therefore, it is important to study the physical properties of EP-POSS. This article studies the physical properties of synthesized EP-POSS, such as the light transmittance, adhesion, flame retardancy, surface energy, and dielectric properties. The results prove that EP-POSS is a hydrophobic material that can be applied to photovoltaic panels. This work laid a theoretical foundation for the application of EP-POSS as a hydrophobic material to photovoltaic panels.
