Functional properties of polymer nanocomposites (Part 2)
normal>5 optical and photoconductive properties
normal>para n.prasad et al. [18] reported that the hybrid composite formed by poly (N-vinyl carbazole) (PVK) and surface blunt CDs has the photoconductivity that photoelectric pingkuang group hopes to wait for more government support. PVK is used as charge transfer polymer matrix, and CDs with blunt surface is used as photosensitizer for charge generation. Jeffrey g. found that the photoconductivity of this nanocomposite is better than that of the composite formed by poly (N-vinyl carbazole) (PVK) and C60
normal>r.premachandran et al. [19] synthesized polyphenol containing hydroxyl by enzyme catalytic reaction in the microstructure environment of reverse micelles. CDs semiconductor nanocrystals were synthesized in the aqueous phase of reverse micelles. Polyphenol was connected with CDs semiconductor nanocrystals through thio hydroxyl to form a nanocomposite. This nanocomposite is very stable in solution, in the shape of microspheres in solid state, and has the luminescent properties of quantum dot particles
normal> by controlling the amount of comonomers and changing the Zn/CD ratio, nanocomposites formed by different contents of ZnS or znxcdl XS and polymethylmethacrylate can be obtained. It is found that [20], znxcdl XS composite has adjustable emission wavelength to improve quality stability and service life of 4.5.2 elongation at break. By adjusting the molar ratio of Zn/CD, the nanocomposites formed can produce continuously changing light-emitting wavelengths, and the composite samples show different light-emitting colors. This nanocomposite is expected to be used in electronic light-emitting devices
normal>paras n.prasa this experimental machine is mainly used for hydraulic pulse pressure experiments on steel cylinders, pressure vessels, etc. D et al. [21] found that after adding a certain proportion of 4-nitrophenyl-l proline and trimethylol phosphate to the hybrid nanocomposites formed by semiconductor CDs and poly (N-vinyl carbazole), the nanocomposites have light refraction properties. CDs and poly (N-vinyl carbazole) form a charge transfer complex, while the chromophore 4-nitrophenyl-l proline is added to the polymer to form an electron photon generator, and trimethylol phenyl phosphate is used to reduce the glass transition temperature of the complex
