Investigation of morphology and rheological propertyes of glassflake/epoxy nanocomposites systems

Epoxy resins are often used for industrial applications because of their good chemical, mechanical, thermal, and electrical properties. One of the most important applications of epoxycoatings is the protection of metal surfaces from environmental attack. Recently, epoxy coatings with inorganicnanofillers are being studied for improved coating performance. In this work, we focus on the addition of nanoglassflake (NGF) in an epoxy coating. One of the importantpart of nanocomposites preparation is dispersion of nanofiller in matrix. The morphology and final properties are completelydependent to this part of processing step. In this work effect of two mixing methods, mechanical mixing and sonication, on dispersion of NGF in epoxy were investigated to find bestmixing method. Then the rheological behaviors of the epoxy/glassflake nanocomposites were investigated in termsof their viscosity, storage modulus (G’), and loss modulus (G ).
