Aggregation‐induced demulsification triggered by the hydrophilic fabric for the separation of highly emulsified oil droplets from water

A functional fabric with hierarchical structure consisting of basalt fibre as a substrate and polyvinyl alcohol coating was developed, aiming at providing low cost high-performance way to separate highly emulsified oil in water. The functioned hydrophilic gate for the penetration water emulsion, whereas micro-channels formed offered capillary force continuous flow synergy these two materials led increase on concentration liquid, which turn enhanced collision droplets aggregate into large ones emulsion resulted separation from Based findings, an aggregation-induced demulsification process proposed explain above phenomenon, mechanism confirmed by studying distribution controlled degree.
