“…As can be seen from Figure 6a, the I−V curves of RGO and RGO-CNT films show obviously ohmic-like characteristics, rather than the Schottky diode feature [27]. As proposed by Patole et al, because of the formation of an extended conjugation network within the CNTs bridging the gaps between the graphene sheets, the conductivity in the hybrid materials can show great improvement [28]. Based on the I−V curves (shown in Figure 6a), one can calculate the corresponding R of RGO and RGO-CNT films.…”

Abstract:Reduced graphene oxide-carbon nanotube (RGO-CNT) hybrid materials were prepared by a simple catalyst-free route. The thermostability, photoluminescence (PL) and electrical properties of RGO-CNTs were investigated systematically. The results revealed that compared to RGO, RGO-CNTs showed multicolor PL, and higher thermostability and conductivity. The RGO-CNTs therefore have important potential applications in the fields of photonic and electrical devices.

“…The absorption bands for polystyrene are as follows: 3026 cm -1 C-H band related to the deformation of the aromatic ring; 2928 and 2851 cm -1 bands related to the asymmetric and symmetric stretching vibrations of CH 2 , respectively; 1600 and 1493 cm -1 C-C bands corresponding to the stretching of the aromatic ring; 1445 cm -1 band related to the bending vibration of CH 2 ; 1069 and 1028 cm -1 C-H bending vibrations of the ring plane; and 760 and 698 cm -1 C-H bands that correspond to the deformation of the aromatic ring out of the plane [27][28][29][30] . No changes were observed in the polystyrene spectra after 90 days of exposure in the simulated soil.…”

Composites consisting of waste cotton yarn (CF) from the textile industry and postconsumer expanded polystyrene (EPS) was followed during 90 days of exposure in simulated soil. The mechanical properties, morphologies and chemical natures of the composites were determined before and after exposure in simulated soil. The composites were made using a single-screw extrusion, a twin-screw extrusion and injection molding. The composites showed an increase of the mechanical properties nearly 50% in relation to the recycled expanded polystyrene (rEPS). After exposure in simulated soil the composites presented losses of mechanical properties. Evidence of the oxidation of the samples was demonstrated by the increase in the values of the carbonyl index after 30 days of exposure in simulated soil. Changes in the color of the surface of the sample were observed after 90 days of exposure and are due to the fungi and bacteria colonization on the surface.

“…In many polymer nanocomposites prepared by using in situ polymerization the decrease of molecular weight and increase of M w /M n was observed. For instance, Patole et al [33,34] have found that It is known that rheological properties of nanocomposites containing layered nanofillers are related to the degree of exfoliation of nanofiller in polymer matrix and also to the level of interfacial interaction between the nanofiller surface and polymer chains [35]. Usually, in nanocomposites the increase of melt viscosity is observed with increasing of nanofiller content due to nanofiller-polymer interactions.…”

a b s t r a c tPoly(trimethylene terephthalate-block-tetramethylene oxide) (PTT-PTMO) copolymer/ graphene oxide nanocomposites were prepared by in situ polymerization. From the SEM and TEM images of PTT-PTMO/GO nanocomposite, it can be seen that GO sheets are clearly well-dispersed in the PTT-PTMO matrix. TEM images also showed that graphene was well exfoliated into individual sheets, suggesting that in situ polymerization is a highly efficient method for preparing nanocomposites. The influence of GO on the two-phase structure, melt viscosity and mechanical properties of PTT-PTMO block copolymer was examined by using DSC, ARES rheometer and tensile tests. The DSC results imply that the introduction of GO did not affect the glass transition temperature of PTMO-rich soft phase, melting temperature of PTT hard phase and degree of crystallinity of the nanocomposites. As the graphene oxide loading in the nanocomposites increase, the enhanced Young's modulus and yield stress was observed. The tensile strength slightly increased with the increase of GO from 0 to 0.5 wt% when elongation at break was higher or comparable to the value of neat PTT-PTMO copolymer.
