Abstract	Controlling the cell size and cell density of microcellular foams has an important influence on polymer-ic foams properties. By using nanoparticles in polymers and supercritical fluids as foaming agent, it is pos-sible to create microcellular foams with controlled morphology. In this article surface modified carbon nanotube (CNT) was used to prepare Polymethylmethacrylate (PMMA) nanocomposite. Dry ice was used as the source of supercritical CO2 in foam production. Microcellular foams were prepared form PMMA/CNT nanocomposites. The cell morphology was observed by scanning electron microscopy (SEM) and the cell size and cell density were calculated via image analysis. The effect of CNT on cell size and cell density of foams was investigated. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35437
