Characterization of Nanoclay Dispersion in Epoxy Matrix by Combined Image Analysis and Wavelength Dispersive Spectrometry

Abstract

Nanoclay has been gaining acceptance as a nano-meter scale reinforcement for polymers during the last two decades [1]. It has proven to be successful for reinforcing thermoplastics [2], however, its utilization in thermosetting resins has been problematic. To improve dispersion of nanoclay into thermosetting resins, a number of companies developed surface modifications, which replace the sodium ions with larger organic molecules. In the current study, we are investigating the dispersion characteristics of three commercially available nanoclays from Southern Clay Products Inc., by combining microscopic image analysis and wavelength dispersive spectrometry.
