چكيده فارسي :
Microcellular polystyrene/nano-ZnO nanocomposite foams were prepared in batch foam process using supercritical CO2 as the blowing agent. At filler concentrations higher than percolation threshold, the addition of nanoparticles reduced cell size and increased cell density significantly. Cell morphology was investigated in two different temperatures of 80 and 120 ̊C to explore the effect of nanoparticles in nucleation mechanism. In higher temperature major changes in cell size was observed.
