Magnetic/antibacterial bifunctional nanoparticles were fabricated through the immobilization of antibacterial N-halamine on silica-coated Fe(3)O(4)-decorated poly(styrene-co-acrylate acid) (PSA) nanoparticles. The samples characterized by scanning electron microscopy (SEM), transmission (TEM), X-ray photoelectron spectra (XPS), diffraction (XRD), energy-dispersive spectrometry (EDX), Fourier transform infrared (FTIR), and thermogravimetric analysis (TGA). was developed from precursor...
A novel type of hydrophobic association hydrogels (HA-gels) was prepared through micellar copolymerization acrylic acid (AA), acrylamide (AAm) as basic monomers and a small amount octylphenol polyoxyethylene ether acrylate with seven ethoxyl units (OP7-AC) monomer. The HA-gels exhibited desirable mechanical property stably reversible phase transition between opaque transparency. influences adding urea varying AA:AAm molar ratio on the behavior were discussed, which indicated that introduced...
Abstract Hydrophobic association hydrogels (HA‐gels) with almost ideal properties were successfully prepared by micellar copolymerization, and the associated micelles acted as physical cross‐linking points in network of HA‐gels. HA‐gels exhibit exceptional mechanical transparency. However, most striking are that possess capability self‐healing remolding, which is mainly due to dissociation re‐association process micelles. Dried‐gels, stretching a certain elongation for period time air, can...
N-halamine-functionalized silica-polymer core-shell nanoparticles with enhanced antibacterial activity were synthesized through the encapsulation of silica as support polymeric N-halamine. The as-synthesized characterized by transmission electron microscopy (TEM), scanning (SEM), energy-dispersive x-ray spectrometry (EDX), dynamic light scattering (DLS), thermogravimetric analysis (TGA), and Fourier transform infrared (FTIR). These displayed powerful performance against both Gram-positive...
Hydrophobic association hydrogels (HA-gels) were prepared through micellar copolymerizationof acrylamide (AM) and a small amount of octyl phenol polyethoxy ether acrylate (OP-4-AC) in an aqueous solution containing sodium dodecyl sulfate (SDS) at 50°C. The resulting HA-gels exhibited excellent mechanical properties transparency. However, the most striking that possessed capability self-healing. investigated by uniaxial stretching. results showed could be varied greatly changing OP-4-AC...
Hybrid microballs with polystyrene cores coated by titania nanoparticles were prepared in miniemulsion polymerization. Acrylic acid was used as a comonomer to promote locating on the polymer's surface. The addition of hydrophobic agent effectively prevents monomer diffusing into aqueous phase. morphology hybrid particles examined transmission electron microscope, and its change pattern reactive conditions observed. infrared spectra showed that there existed certain interaction between...
Antimicrobial composites with a well-defined core−shell nanostructure were prepared through immobilization of N-halamine on polystyrene-functionalized silica nanoparticles. Evidence for onto polystyrene-modified has been inferred from different techniques like transmission electron microscopy (TEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), zeta potential analyses, and Fourier transform infrared (FTIR). Experimental results...
Monodisperse magnetizable silica composite particles were prepared from heteroaggregates of carboxylic polystyrene latex and Fe(3)O(4) nanoparticles. It was found that the heteroaggregation nanoparticles is dependent on pH solution. At low value (pH = 2-4), aggregation proceeds effectively due to opposite charges surfaces magnetic high (pH>8), no observed negative charge both surface The heteroaggregate be stable in a wide range values, existence coordination interactions at interface After...
Abstract We report a simple route for the effective synthesis of Ag@TiO 2 nanoparticles in water‐in‐oil (w/o) emulsions and provide detailed characterization materials with TEM, TG‐DTA, IR, XRD, SPS measurements. Such core‐shell hybrid can be fabricated two steps: formation silver core by reduction Tollens reagent glucose water phase, hydrolysis Ti(OC 4 H 9 ) at water/oil interface amorphous TiO shell. The procedure led to nanocomposites crystalline size range from 5 15 nm diameter an shell...
Poly(vinyl alcohol) (PVA) hydrogels were prepared in aqueous solutions at different concentrations using glutaraldehyde (GA) as cross-linker. The gel fraction, increase rate of gels, critical point, and swelling ratio measured. Furthermore, the influences intramolecular cyclization on cross-linking processes structure formed studied. results show that degree [−CHO]/[−OH] point (rc) with decrease PVA concentration. bulk gels do not form when concentration is below 1.1 × 10-2 g/mL even higher...
