Polyacrylamide-grafted magnetic reduced graphene oxide nanocomposite: preparation and adsorption properties
Published in Colloid and Polymer Science
Magnetic reduced graphene oxide/polymer nanocomposites were prepared by in situ polymerization and grafting of polyacrylamide on the surface of functionalized magnetic reduced graphene oxide (rGO). Graphene oxide nanosheets were decorated with Fe3O4 nanoparticles, reduced and functionalized with 3-(trimethoxysilyl)propyl methacrylate, and then graf...
Effect of nano-SiO2 and surfactants on the oil-water interfacial properties
Published in Colloid and Polymer Science
This study aimed to clarify the effects of different types of nano-SiO2 and surfactants on the oil-water IFT and IFR. These interfacial properties were demonstrated to be influenced by the interaction between the surfactant, the nano-SiO2 and the oil component. The interaction between nano-SiO2 and oil components and their adsorption at the crude o...
pH optimization for high-efficiency PEGylation of gold nanorods
Published in Colloid and Polymer Science
The use of methoxy polyethylene glycol thiol (mPEG-SH), in conjunction with additives, is one of the most straightforward, versatile, and widely used methods for modifying gold nanorods (GNRs), especially for applications in the field of biomedicines. The decreased toxicity of PEGylated GNRs is critical for investigating cell-nanomaterial interacti...
Formation of polyelectrolyte multilayer films with controlled wettability via layer-by-layer electric-assembly
Published in Colloid and Polymer Science
Taking the positive charged poly (diallyldimethylammonium chloride), PDDA, and negative charged polymaleic acid, PMA, as raw materials, the polyelectrolyte multilayer film, PMF, with oppositely charged surfaces was prepared by the layer-by-layer electric-assembly, LBLEA, method. Experimentally, the applied voltage was varied and the electrostatic f...
Fabrication of carboxyl-functionalized polymer microtubes via RAFT copolymerization of diurea-type xerogel fibers and ac...
Published in Colloid and Polymer Science
A new diurea-type gelator was synthesized from 2-isocyanoethyl acrylate and 4′-diaminodiphenylmethane, which formed supramolecular gel in acetonitrile driven by hydrogen bonds. The xerogel fibers with a smooth lamellar structure were used as templates and monomer source in fabricating polymer microtubes via reversible addition-fragmentation chain t...
A Cu-free clickable surface with controllable surface density
Published in Colloid and Polymer Science
A Cu-free clickable polymer was synthesized and used to dip-coat plastic substrates to prepare Cu-free clickable surfaces. The surface density of dibenzocyclooctyne moieties was quantified using an azide-conjugated fluorophore and a conventional fluorometer, indicating that the clickable moieties displayed on a dip-coated surface were accessible fr...
Characterization of PMMA-b-PDMAEMA aggregates in aqueous solutions
Diblock amphiphilic copolymers form aggregates in some solvents. Such aggregates exhibit different morphologies, depending mainly on the polar/apolar block ratios. Aggregation of copolymers with polar block excess leads to micelle-like aggregates, known as polymeric micelles, which can be used as vehicles for drug and gene delivery, water decontami...
Effect of powder properties on the physicochemical and rheological characteristics of gelation inulin–water systems
Published in Colloid and Polymer Science
This study investigates the influence of physical properties of powder on the potential functionality of inulin as a polymeric gelator. Inulin powder was characterized using high-performance anion exchange chromatography, wide-angle X-ray, and particle size. Moreover, the inulin–water system was described using rheological properties, optical micro...
Covalent modification of graphene oxide by 4,4′-methylenebis(phenyl isocyanate) to enhance corrosion resistance of polys...
Published in Colloid and Polymer Science
Functionalized graphene oxide (MDI-GO) was prepared by grafting of 4,4′-methylenebis(phenyl isocyanate) onto graphene oxide. X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy revealed that 4,4′-methylenebis(phenyl isocyanate) (MDI) was successfully bonde...
