Abstract
AbstractEpoxy/TEIA clay nanocomoposite was synthesized from renewable resource based itaconic acid trifunctional bioresin (TEIA) reinforced with Cloisite 93 A nanoclay (C93 A), which was further cured with an anhydride curing agent and 2‐methylimidazole as a catalyst. From the mechanical strength it was observed the tensile strength of virgin epoxy 42.94 MPa enhanced to 70.26 MPa with the incorporation of 2.5 wt% C93 A. Differential scanning calorimetry, thermal analysis, and dynamic mechanical analysis demonstrated that epoxy/30%TEIA with 2.5 wt% organoclay content revealed improvement of the thermal stability and storage modulus. Epoxy/30%TEIA/2.5%C93 A showed raised surface hydrophilicity and increased the wetting energy with increasing clay content. Transmission electron microscopy (TEM) and X‐ray diffraction (XRD) studied corroborated that exfoliated formation within the organoclays in the nanocomposites.
