Preparation of PDVB/TiO2 composites and the study on the oil-water separation and degradation performances
The traditional superhydrophobic materials are not ideal for treating residual pollutants after oil-water separation. In this paper, a simple and economical method was developed for the fabrication of multi-functional superhydrophobic materials PDVB x /TiO 2 composites, through in situ polymerization. The performance of the superhydrophobic composite was studied. The results showed that the low surface energy of PDVB 2.5 /TiO 2 composite with the micro-nano scale roughness would result in excellent superhydrophobicity. In addition, the PDVB 2.5 /TiO 2 composite exhibits optimum effect on the degradation of methyl orange (MO) with the degradation efficiency of 97.8%. What is more, the applications of the composite materials could be expanded to other fields, such as the degradation of drug ciprofloxacin hydrochloride (CIP). Finally, we expanded the application of the PDVB x /TiO 2 composites to tribology, and found its excellent performance in reducing wear and antiwear.
