The Effect of CNT Surface Modification on the Foam Morphology

The growing interest in using of novel polymer microcellular foams with cell size less than 10μm and cell density greater than 108cell/cm3 is mainly due to their advantages [1].Recently, using nano scaled additives has been considered to improve cell nucleation and produce more bubbles with a finermorphology. Incorporation of nanoparticles such as layered silicate, carbon nano fiber and carbon nano tube in foam production have been reported [2].In this study nanocomposite foam based on thermoplastic poly urethane/ polyvinyl chloride/ multi wall carbon nano tube (TPU/PVC/MWNT)were produced via batch method and the effect of functionalization of CNT was studied on the foam morphology.
