A scalable method toward superhydrophilic and underwater superoleophobic PVDF membranes for effective oil/water emulsion separation
A superhydrophilic and underwater superoleophobic PVDF membrane (PVDFAH) has been prepared by surface-coating of a hydrogel onto the membrane surface, and its superior performance for oil/water emulsion separation has been demonstrated. The coated hydrogel was constructed by an interfacial polymerization based on the thiol-epoxy reaction of pentaerythritol tetrakis (3-mercaptopro...

Single Emulsion Microfluidic Production of Janus and Core-Shell Particles via Off-chip Polymerization
In this work, we describe a straightforward approach to produce monodisperse Janus and core-shell particles by using organic solvent free single emulsion droplet-based microfluidic device combining with off-chip polymerization. To accomplish this, methyl methacrylate (MMA) was used as both the oil phase and solvent to dissolve a polymerizable PEG-based macromolecular surfactant, instead of t...

The controllable preparation of porous PLGA microspheres by the oil/water emulsion method and its application in 3D culture of ovarian cancer cells
In this study, we prepared surface-smooth and porous poly(lactic-co-glycolic acid) (PLGA) microsphereswith different diameters, different sizes of pores and different densities of pores using a simple oil/wateremulsion method and varying the preparation conditions, including the molecular weight of PLGA, thecomponents of the PLGA and the addition of porogen. The surface-smooth nonporous and porous...

Synthesis of Triblock Copolymers via RAFT Polymerization and Their Application as Surfactants for Crude Oil in Water Emulsion
As surfactants for crude oil emulsions, poly[N,N-(dimethylamino) ethyl methacrylate-b-poly(ethylene glycol) methyl ether methacrylate-b-lauryl methacrylate] (PDMA-b-PPMA-b-PLMA) triblock copolymers were synthesized via reversible addition?fragmentation chain transfer (RAFT) polymerization and characterized by gel permeation chromatography and proton nuclear magnetic resonance spectroscopy. The cop...

A green strategy to enhance a liquid-liquid heterogeneous reaction by magnetic recyclable pickering emulsion
This work described a general strategy to enhance a typical organic-aqueous heterogeneous green oxidation reaction by introducing surface tunable magnetic nanoparticles into liquids to form a controllable Pickering emulsion. We synthesized cross-linked polystyrene (PS)-covered Fe3O4 nanoparticles grafting with different N-alkyl imidazoles, and systematically discus...

Facile one-step fabrication of polymer microspheres with high magnetism and armored inorganic particles by Pickering emulsion polymerization
Facile one-step Pickering emulsion polymerization was employed to prepare magnetic polymer microspheres with high magnetism and armored inorganic particles. Partially hydrophilic CTAB-modified Fe3O4 particles were employed as stabilizer of Pickering emulsion and were armored on the as-prepared microspheres, while totally hydrophobic oleic acid-modified Fe3O4 particles were encapsulated...

A Comparative Study of PMMA/Mesoporous Silica, PMMA/Clay, and PMMA/Colloidal SiO2 Nanocomposites Made by Emulsion Polymerization
PMMA/mesoporous silica
nanocomposites were prepared via in-situ emulsion polymerization of methyl
methacrylate and a large pore size MSU-F silica. PMMA/clay, PMMA/colloidal SiO2 nanocomposites, and pure PMMA were also made by same method. The thermal stability
and mechanical properties were characterized by thermogravimetric analysis, differential
scanning calorimetry, and dynamic mechanical ana...
