Achieving high stability and anti-adherence performance of ZrO2 ceramic product via hydrophobic modified surface
ZrO2 is widely used. However, surface hydrophilicity is harmful to waterproof devices. In this work, epoxy-based polyhedral oligomeric silsesquioxane (POSS) was chemically bonded to ZrO2 sheet surface for weather-resistant hydrophobicity and anti-adherence property. First, ZrO2 sheet was modified with hydroxyls, followed by amino modification. Then, surface POSS modification was performed via ring-opening addition. Next, composition and micro-morphology of POSS-treated sheet were clarified. Ultimately, the dependence of water contact angle of POSS-modified sheet on POSS solution treating time was researched, and the highest contact angle of 132.6° was gained by 24-h treating. Acid corrosion, alkali corrosion, and ultraviolet radiation for 48 h were employed to verify good weather resistance with contact angles over 120°. POSS-modified sheet had good anti-adherence capacity. Cooperation of POSS and ZrO2 was utilized to obtain low surface energy and high surface roughness. This work might help to obtain hydrophobic ceramics as catalyst supports for oil-phase reactions.
