title = "Effect of block copolymer coated nanoclay on polystyrene foams under supercritical carbon dioxide",
abstract = "Polystrene-b-polymethyl methacrylate (PS-b-PMMA) was end-tethered on Montmorillonite (MMT) by atom transfer radical polymerization (ATRP) to make exfoliated nanoclay composites. These nanocomposites were mixed with polystyrene (PS) by melt blending. The mixtures were then batch formed with supercritical CO2. It was found that the cell density of foams based on these blends with 1 wt% modified MMT is higher than that based on neat PS and PS compounded with neat PMMA or PS-b-PMMA at the same foaming conditions. The presence of nanoclay dramatically increases the viscosity of the mixture. The heterogeneous nucleation effect of the nanoclay and nanocomposites will be discussed.",
