Hierarchical, Self-Healing and Superhydrophobic Zirconium Phosphate Hybrid Membrane Based on the Interfacial Crystal Growth of Lyotropic Two-Dimensional Nanoplatelets
We demonstrate a
facile route to in situ growth of lyotropic zirconium phosphate (ZrP)
nanoplates on textiles via an interfacial crystal growing process.
The as-prepared hybrid membrane shows a hierarchical architecture
of textile fibers (porous platform for fluid transport), ZrP nanoplatelets
(layered scaffolds for chemical barriers), and octadecylamine (organic
species for superhydrophobic functionalization). Interestingly, such
a hybrid membrane is able to separate the oily wastewater with a high
separation efficiency of 99.9%, even at in harsh environments. After
being chemically etched, the hybrid membrane is able to restore its
hydrophobicity autonomously and repeatedly, owing to the hierarchical
structure that enables facile loading of healing agent. We anticipate
that the concept of implanting superhydrophobic self-healing features
in anisotropic structure of lyotropic nanoparticles will open up new
opportunities for developing advanced multifunctional materials for
wastewater treatment, fuel purification, and oil spill mitigation
