The synthetic procedures for preparation of free-standing and attached to polymer support surface-modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due charge transfer complex formation were developed. one-step synthesis colloids consisting NPs is based on reaction between titanium(IV) isopropoxide (TTIP) lauryl galatte in nonprotic organic solvents (tetrahydrofuran, xylol, chloroform). poly(GMA-co-EGDMA) copolymer decorated was obtained two steps....
The benefit of being acquainted with thermal properties, especially the stability polyurethanes (PU), and simplified methods for their improvement is manifold. Considering this, effect embedding different amounts unmodified surface-modified TiO2 nanoparticles (NPs) within PU, based on polycaprolactone (PCL) Boltorn® aliphatic hyperbranched polyester, PU properties was investigated. Results obtained via scanning electron microscopy, swelling measurements, mechanical tests thermogravimetric...
The mechanical properties of nanocomposites obtained by incorporation fairly uniform hematite nanorods (?-Fe2O3 NRs) into epoxy resin were studied as a function the content inorganic phase. A thorough microstructural characterization ?-Fe2O3 NRs and was performed using transmission electron microscopy (TEM) atomic force (AFM). TEM measurements revealed rod-like morphology nanofiller with size distribution (8.5 nm?170 nm, diameter?length). High-magnification AFM indicated agglomeration...
Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B6) was found to alter optical properties. Microstructural characterization involving transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis revealed that anatase TiO2 NPs had a narrow size distribution an average diameter 45 ?. The absorption onset surface-modified samples red-shifted by about 0.4 eV compared unmodified particles....
The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. were investigated using FTIR UV-Vis spectroscopy, which confirmed the formation charge transfer complex between imine by reaction Ti atoms hydroxyl groups a modifying agent. further applied as filler for preparation epoxy nanocomposites. Thermal mechanical properties prepared nanocomposites examined dynamic mechanical analysis, differential scanning...
