Effects of organoclay modifiers on the flammability, thermal and mechanical properties of polycarbonate nanocomposites filled with a phosphate and organoclays

Influence of the modification, induced by zirconia nanoparticles, on the structure and properties of polycarbonate

“…Some authors found that the well dispersed metal oxide nanoparticles in PC improved its surface, viscoelastic, and mechanical properties, and increased its thermal stability. They related these observations to the strong interactions at the polymer-filler interface [8][9][10][11].…”

“…PC nanocomposites have shown potential applications in UV protecting sheets and films [1][2][3][4]. There are a number of recent papers reporting on the mechanical properties, thermal stability and flame retardancy of PC nanocomposites containing different metal oxide nanoparticles [5][6][7][8][9][10]. The results indicate that metal oxides have an effect on the morphology, as well as mechanical and thermal behavior of PC.…”

Polymer degradation during the melt processing of clay reinforced polycarbonate nanocomposites

“…It must be considered, on one hand, that the organic modifier of C15 is a quaternary ammonium salt. Due to its low thermal stability, this modifier will suffer the Hoffmann elimination to form an amine and the corresponding olefin, thus generating acidic sites on the clay [20,31], in a process which takes place at temperatures similar to those used in the melt processing of polycarbonate nanocomposites. Thus, during the melt compounding of the nanocomposites, some acidic sites are generated on the silicate layers, which catalyze the hydrolytic degradation of PC.…”

The processing of polycarbonate nanocomposites generated with various nanofillers

“…Some investigations prepared the materials by in situ polymerization (Rama and Swaminathan, 2010;Yoo et al, 2004) and others by polymer melt intercalation (Yoon et al, 2003a,b;Carrión et al, 2008;Nevalainen et al, 2009;Feng et al, 2012;Xiao et al, 2013;Suin et al, 2013Suin et al, , 2014Hsieh et al, 2004;Lee and Han, 2003).
