Oil-polluted water is a worldwide problem due to the increasing industrial oily wastewater and the frequent oil spill accidents. Here, we report a novel kind of superhydrophilic hybrid membranes for effective oil/water separation. They were prepared by depositing CaCO3-based mineral coating on PAA-grafted polypropylene microfiltration membranes. The rigid… (More)
Patterned porous films containing enzymes have been facilely prepared via a one-step breath figure process, which is based on the self-assembly of horseradish peroxidase nanoparticles that show good resistance to organic solvents. The patterned biohybrid films possess robust catalytic activity.
We report on the synthesis and application of a new hydrogel based on a methacrylate substituted polyphosphazene. Through ring-opening polymerization and nucleophilic substitution, poly[bis(methacrylate)phosphazene] (PBMAP) was successfully synthesized from hexachlorocyclotriphosphazene. By adding PBMAP to methacrylic acid solution and then treating with UV… (More)
Fluorescence-switch-based logic devices are very sensitive compared with most of the reported devices based on UV/Vis absorption systems. Herein, we demonstrate that a simple molecule, 5,10,15,20-tetra-(4-aminophenyl)porphyrin (TAPP), shows protonation-induced multiple emission switches through intramolecular charge transfer and/or aggregation-caused… (More)
We present a novel approach to constructing glycosylated surface for microporous membrane. Carbohydrate derivative can be facilely bound onto the alkyne-modified membrane surface via thiol-yne click chemistry. The glycosylated membrane surface shows an excellent affinity adsorption to lectin on the basis of carbohydrate-protein recognition.
