Optimization of preparation process and characterization for hydrophobic α-Al2O3 ceramic membrane

Hydrophobic α-Al2O3 ceramic membrane (HCM) offers excellent mechanical properties, corrosion resistance, and high-temperature resistance. Application of HCM in the membrane distillation (MD) process could expand the application scope of MD equipment and greatly lengthen the replacement cycle of the membrane. Here a prediction model of the contact angle of HCM was constructed by physical-chemical combined modification method, orthogonal method,...
