This work is prompted this website by recent work on single-walled CNTs and UDD ensemble [Gupta et al., J. Appl. Phys. 107, 104308 (2010)] where radiation-induced microscopic defects seem to be stabilized by UDD. The present experiments show similar effects
where these hybrids display only a minimal structural modification under the maximum dose. Quantitative analyses of multiwavelength Raman spectra revealed lattice defects induced by irradiation assessed through the variation in prominent D, G, and 2D bands. A minimal change in the position of D, G, and 2D bands and a marginal increase in intensity of the defect-induced double resonant Raman scattered D and 2D bands are some of the implications suggesting the radiation coupling. The in-plane correlation length (L(a)) was also determined following Tunistra-Koenig relation buy IPI-145 from the ratio of D to G band (I(D)/I(G)) besides microscopic stress. However, we also suggest the following taking into account of intrinsic
defects of the constituents: (a) charge transfer arising at the interface due to the difference in electronegativity of MWCNT C sp(2) and UDD core (C sp(3)) leading to phonon and electron energy renormalization; (b) misorientation of C sp(2) at the interface of MWCNT and UDD shell (C sp(2)) resulting in structural disorder; (c) softening or violation of the q similar to 0 selection rule leading to D band broadening and a minimal change in G band intensity; and (d) normalized intensity of D and G bands Panobinostat cell line with 2D band help to distinguish defect-induced double resonance phenomena. The MWCNT when combined with nanodiamond showed a slight decrease in their conductance further affected by irradiation pointing at relatively good interfacial contact. Furthermore, owing to high thermal and electrical conductivity properties, they can facilitate potentially efficient heat-transfer applications and some results deduced
using Nielsen’s model is provided. (c) 2011 American Institute of Physics. [doi:10.1063/1.3524187]“
“The brittleness of poly(styrene maleic anhydride) (SMA) was improved by compositing with elastic poly(methyl methacrylate-butadiene-styrene) (MBS) to develop it into optical film. Transparent and flexible SMA films were prepared, and the flexibility of them was checked by folding endurance test and folding bend. The transparence of SMAMBS films were proved by the transmittance and haze measurements. In actual view, the letters could be clearly observed while they were covered by prepared films. The thermal stability of them was confirmed by DSC and TGA analysis. These physical properties of films are comparable to that of polycarbonate which is widely used as optical film.
