Octasilsesquioxane-reinforced DGEBA and TGDDM epoxy nanocomposites: Characterization of thermal, dielectric and morphological properties

“…Furthermore, the nano-scale dispersion of POSS cages in epoxy matrices is an important factor to contribute the enhanced thermal stability. The similar results were also observed in our previous work on the completely exfoliated clay-epoxy nanocomposites [32].…”

“…This could be inferred from the DSC and DMA results of the nanocomposites which contain higher loadings of POSS (< 3 wt%). A second cause is that the thermally stable inorganic silica core of POSS molecules are simply less polar than the polymer segments, which in turn reduces the dielectric constant and dielectric loss of the epoxy nanocomposites [32]. In particular, the small amount of POSS (≤ 3 wt%) loading in the hybrid systems illustrates the low dielectric constant and low dielectric loss as shown in Table 1 even attaining higher crosslink densities than those of the neat epoxy systems.…”

Morphological characterization and electrochemical/electrical properties of poly(N‐vinyl carbazole)/montmorillonite composites

“…In addition, in the case of the organically‐modified MMTs the two peaks around 2,924 and 2,854 cm −1 along with the one at 1,465 cm −1 reflect the asymmetric and symmetric stretching vibrations and, bending vibration modes of methylene units, respectively (Fig. 1) [24, 25]. The peaks at 1,600−1,450 cm −1 for aromatic stretching and aromatic CH in plane bending and, the band at 750 cm −1 for aromatic CH out of plane bending are characteristic for PNVCz.…”

Facile synthesis of thermally reduced graphene oxide-sepiolite nanohybrid via intercalation and thermal reduction method

“…Graphite powder was purchased from Sigma-Aldrich with particle size of 10 μm. Sepiolite clay mineral was purchased from Sigma-Aldrich and was further purified using NaCl solution, as reported elsewhere (Nagendiran et al, 2008).…”
