A self-cleaning polybenzoxazine/TiO2 surface with superhydrophobicity and superoleophilicity for oil/water separation

摘要: Two important properties-the low surface free energy of polybenzoxazine (PBZ) and the photocatalysis-induced self-cleaning property titanium dioxide (TiO2) nanoparticles-are combined to develop a promising approach for oil/water separation. They are integrated into multifunctional superhydrophobic superoleophilic material, PBZ/TiO2 modified polyester non-woven fabrics (PBZT), through simple dip coating subsequent thermal curing method. The resulting PBZT reveals excellent mechanical durability strong resistance ultraviolet (UV) irradiation as well acid alkali. This durable fabric is efficient separating mixtures by gravity with high separation efficiency, it can also purify wastewater that contains soluble dyes, which makes more effective in treating water pollution. Importantly, demonstrates an performance on removal both oil particle contamination. It expected this process be readily adopted design based materials
