Hybrid nylon-6/silica nanocomposites with improved mechanical properties Monserrat García, Werner E. van Zyl, and Henk Verweij1 Inorganic Materials Science Group, MESA+ Research Institute, University of Twente P.O. Box 217, 7500 AE Enschede, The Netherlands 1 Department of Materials Science and Engineering, The Ohio State University, Columbus, OH 43210-1178, USA. ABSTRACT The study involves the development of new strategies to form technically interesting hybrid nanocomposites with improved mechanical properties. In particular, a new ‘dissolution’ preparative route was developed which incorporates silica nanoparticles (0.5 were obtained. Furthermore, the addition of nano-silica to the PA-6 led to a lowering of the coefficient of friction and the wear resistance was improved. The minimun wear rate between the samples was obtained with 2wt% of filler addition. ACKNOWLEDGMENTS The authors would like to thank B.A.G. Schrauwen for the performance of the mechanical tests B. J. Kooi and J.T. De Hosson for the TEM pictures, H. Koster for the XRD measurements and L. Vrielink for the XRF characterization.
