We show that incorporating nanofillers with higher hydrophobicity promotes better dispersion of nanofiller in TPU matrix due to greater interaction between the nanofiller and the hydrophobic PDMS soft segment in this ElastEon TPU system. The nanocomposite with the most hydrophobic surface modification demonstrates the best nanofiller dispersion and intercalation and hence resulted in an overall best mechanical and thermomechanical properties when incorporated in 2 wt%. These findings show that the polarity matching between the TPU and the nanofiller determines the nanofiller-TPU interactions and thus the mechanical properties of the produced nanocomposites. 2014-06-10T08:21:51Z 2014-06-10T08:21:51Z 2013-09 Article Advanced Materials Research, vol. 795, 2013, pages 9-13 978-303785811-0 1022-6680 (Print) 1662-8985 (Online) http://www.scientific.net/AMR.795.9 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35330 10.4028/www.scientific.net/AMR.795.9 en Trans Tech Publications
