Sustainable thermoplastic elastomers derived from plant oil and their “click-coupling” via TAD chemistry
We report the preparation of plant oil based triblock copolymers based on soybean oil monomers. The
monomers were polymerized via atom transfer radical polymerization with subsequent chain extension, resulting in poly(styrene-b-soybean oil acrylate-b-styrene) (PS-b-PSBA-b-PS) and poly(styreneb-soybean oil methacrylate-b-styrene) (PS-b-PSBMA-b-PS) triblock copolymers. These polymers...

【Nanoscale】Ultrasonication assisted preparation of carbonaceous nanoparticles modified polyurethane foam with good conductivity and high oil absorption properties
In this work, we report a facile, low cost and time-saving method for the fabrication of compressible, electrically conductive, oil absorptive, cost-effective and flexible polyurethane (PU) foam through ultrasonication induced carbonaceous nanoparticles (CNP) onto flexible PU foam (CNP-PU foam). SEM images showed that the CNP could be firmly anchored onto the PU foam, and made the PU foam surface ...

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...

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...

[ACS Appl. Mater. Interfaces] Janus Polymer/Carbon Nanotube Hybrid Membranes for Water/Oil Separation
A robust and simple method is provided to fabricate Janus polymer/carbon nanotubes (CNTs) hybrid membranes for oil/water separation. Starting from CNTs membranes formed by dispensing, hydrophobic poly (styrene) (PS) and hydrophilic poly(N, N-dimethylaminoethyl methacrylate) (PDMAEMA) were grated from different sides of the photo active CNTs membranes via self-initiated photografting and photopolym...

Poly(dimethylsiloxane) Oil Absorbent with a Three-Dimensionally Interconnected Porous Structure and Swellable Skeleton
Cleanup of oil spills is a worldwide challenge to prevent serious environmental pollution. A new kind of poly(dimethylsiloxane) (PDMS) oil absorbent with high absorption capacity and excellent reusability was prepared and used for oil/water separation. The preparation process of PDMS oil absorbents involves direct curing of a PDMS prepolymer in a p-xylene solution in the presence of commercial s...
