Synthesis of clay–carbon nanotube hybrids: Growth of carbon nanotubes in different types of iron modified montmorillonite

Drastic increase in catalyst productivity of nanoclay-supported CVD-grown carbon nanotubes by organo-modification

“…Synergistic action of clay CNT in improving water vapor adsorption capability and electrical behavior properties of polylactide was also reported (Santangelo et al, 2011a). A wide variety of precursor gases utilized as carbon source for NC/CNT hybrids such as acetylene (Gournis et al, 2002;Lu et al, 2005;Zhang et al, 2006;Manikandan et al, 2012b), ethylene (Destree et al, 2007;Zhang et al, 2009;Madaleno et al, 2012), propylene (Zhang et al, 2009), cyclohexane (Zhang et al, 2009), ethanol (Purceno et al, 2011), isobutane (Milone et al, 2010;Santangelo et al, 2010Santangelo et al, , 2011a, methane (Kadlecikova et al, 2008;Breza et al, 2012;Pastorková et al, 2012) and liquefied petroleum gas (LPG) (Zhao et al, 2011).…”

Evaluation of the anisotropic mechanical properties of reinforced polyurethane foams

“…Rigid, closed-cell PU foams and the precursor components for producing these foams 115 (methylene diphenyl diisocyanate and polyol blends) were obtained from the industrial producer, 116 Montmorillonite-carbon nanotube hybrid nanoparticles were produced by chemical vapour 120 deposition (CVD) onto iron modified montmorillonite [26]. The pre-exfoliated morphology of 121 these hybrid nanoparticles has been observed to result in good dispersion within polymer 122 matrices [27].…”

The Effect of Multiwalled Carbon Nanotubes on the Thermal Conductivity and Cellular Size of Polyurethane Foam

“…In general, a cell size reduction of PU foam caused by the presence of nanoparticles has been reported previously [4]. MWCNTs played as a nucleation point for cell formation and growth of PU foam [24], leading to the creation of a larger number of cells; thus, the cell size became smaller. On the other hand, the viscosity of the foam nanocomposites seems to be higher than PU foam due to the incorporation of MWCNTs with PU matrix which limits the cell growth and results in smaller cell sizes when compared to the PU foam [4].…”
