Abstract
This study aims to improve nanofiller dispersion in epoxy resins by using the electrostatic disperser (ED) as well as to reduce the cost, by using combination of micro- and nano- fillers. The ED method aids in homogenized mixing of nanofillers in epoxy resin, due to its jet elongation and shearing effect on polymer mix. In this context, two concentrations (7.5 wt % and 5 wt %) of nano-silica are used and their rheological properties are tested, before and after the addition of 50 wt% micro-silica. A plausible mechanism of filler dispersion is explained for ED and high shear (HS) methods. It is observed that electrostatic dispersion method aids in network formation of nano-silica, unlike high shear method wherein clusters of nano-silica are formed. Hence ED method aids in reducing the viscosity values with the addition of micro-silica, which is helpful in product molding process. The flexural strength and heat deflection temperature lie in same range for both composites prepared using ED and HS methods.
