摘要:
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 PDVBx/TiO2 composites,through in situ polymerization.The performance of the superhydrophobic composite was studied.The results showed that the low surface energy of PDVB2.5/TiO2 composite with the micro-nano scale roughness would result in excellent superhydrophobicity.In addition,the PDVB2.5/TiO2 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 PDVBx/TiO2 composites to tribology,and found its excellent performance in reducing wear and antiwear.
