Biomimetic leaf wax layer self-healing superhydrophobic MOF sponge with dual applications: High-capacity oil adsorption and efficient cationic dye elimination
In this work, a multifunctional biomimetic self-healing superhydrophobic MOF sponge (HDTMS@UiO-66-NH2@PDA@MS) was prepared for efficient oil-water separation and cationic dye wastewater removal. A PDA layer was formed on the surface of the sponge by DA oxidation and self-polymerization, and UiO-66-NH2 was loaded onto the melamine sponge. To further enhance the hydrophobic properties of the MOF sponge, cetyltrimethoxysilane (HDTMS) is hydrolyzed and condensed to form a non-toxic layer of low surface energy polysiloxane adhesive on the surface of the sponge. The prepared modified sponge exhibited excellent superhydrophobicity (water contact angle of 156.2°), high oil adsorption capacity (73.2–164.7 g/g), and cationic dye removal rate (more than 95 %). Inspired by the self-heal mechanism of the wax layer on plant leaves, the modified sponge and can achieve rapid self-heal at 250 °C after simulated oxidative damage. In addition, the synergistic effects of excellent oil-water separation efficiency, reusability, environmental stability, self-cleaning capabilities make HDTMS@UiO-66-NH2@PDA@MS a promising candidate for marine oil spill remediation and oily wastewater treatment.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
