[Polymer] Large complex micelles formed from amphiphilic H-shaped terpolymers with adjustable block ratio by ultrasonic vibration
Large complex micelles based on H-shaped terpolymers (poly(ethylene glycol))(poly(N,N-dimethylaminoethyl methacrylate))-polytetrahydrofuran-(poly(N,N-dimethylaminoethyl methacrylate)) (poly(ethylene glycol)) ((PEG)(PDMA)-PTHF-(PDMA)(PEG)), with proper block ratio, are obtained through ultrasonic vibration. However, similar micellar morphology is not found using other traditional m...

Gradiently Varied Chain Packing/Orientation States of Polymer Thin Films Revealed by Polarization-dependent Infrared Absorption
Gradiently varied chain packing/orientation states of the polyacrylamide (PAL) thin films spin-coated on the gold (Au) substrates were found via the polarized reflection-absorption fourier transform infrared spectroscopy (RA-FTIR). As the film thickness increases, the splitted amide I bands provide a direct evidence that the PAL thin films are of a gradiently varied bi-layered structure. I...

A comparative study of viscoelastic planar contraction flow for polymer melts using molecular constitutive models
The benchmark problem of planar contraction flow is often used to evaluate the stability of numerical algorithms and the predictability of viscoelastic constitutive models in predicting the rheological behavior of polymer fluids. In this paper, for the simulation of planar contraction flow, the single/simplified modified double convected Pom–Pom (S–MDCPP) model recently proposed is adopted, an...

Enhanced water retention and proton conductivity of the proton exchange membranes by incorporating hollow polymer microspheres grafted with sulfonated polystyrene brushes
Hollow polymer microspheres grafted with sulfonated polystyrene brushes
(HPSS) were synthesized via combination of surface-initiated atom transfer
radical polymerization (SI-ATRP) of styrene from SiO2@P(MAA-co-DVB-co-CMSt)
core-shell microspheres, sulfonation of the polystyrene brushes, and finally
removal of the silica core. These HPSSs were then incorporated into the
sulfonated poly(ether e...

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...

Fast and facile fabrication of porous polymer particles via thiol–ene suspension photopolymerization
A fast and facile method of preparing porous polymer particles via thiol–ene suspension photopolymerization was studied. The porous particles were fabricated by adding the porogen to the click chemistry system. In this paper, the photopolymerization of dipentaerythritol hexakis (3-mercaptopropionate), pentaerythritol tetrakis (3-mercaptopropionate), 1,3,5-tri-2-propenyl-1,3,5-triazine...

Preparation and characterization of bovine serum albumin surface-imprinted thermosensitive magnetic polymer microsphere and its application for protein recognition
A novel bovine serum albumin surface-imprinted thermosensitive magnetic composite microsphere was successfully prepared by the surface grafting copolymerization method in the presence of temperature-sensitive monomer N-isopropylacrylamide (NIPAM), functional monomer methacrylic acid (MAA) and cross-linking agent N,N′-methylenebisacrylamide (MBA). The structure and component of the thermosensiti...

Scalable preparation of multiscale carbon nanotube/glass fiber reinforcements and their application in polymer composites
The introduction of carbon nanotubes (CNTs) into conventional fiber
to construct a hierarchical structure in polymer composites has attracted great
interest owing to their merits of performance improvement and multiple
functionalities. However, there is a challenge for realizing the scalable preparation
of the multi-scale CNT-glass fiber (CNT-GF) reinforcements in practical
application. In this wo...
