Zirconium Tungstate Nanoparticle Synthesis and Functionalization for Coefficient of Thermal Expansion Reduction of DGEBA/ED757 Epoxy Substrate
Abstract
Zirconium tungstate (ZrW2O8) nanoparticles (NPs) were synthesized, functionalized, and dispersed into DGEBA/ED757 epoxy resin to decrease the coefficient of thermal expansion (CTE) of the epoxy resin.
The sol-gel method was used to synthesize the NPs.1-2 After synthesis, the surface of the particles was subjected to ligand exchange with silane ligands containing amine or epoxy groups to promote covalent attachment to the epoxy resin during polymerization. The particles were characterized using thermogravimetric analysis (TGA), x-ray diffraction (XRD), and transmission electron microscopy (TEM). The NPs synthesized were found to be 61% ZrW2O8 and 38.1% WO3 from quantitative XRD analysis.
The CTE of the epoxy samples was found using a thermomechanical analyzer (TMA). Results of the study concerning CTE reduction are ongoing, as are studies to ensure appropriate surface ligand coverage of the NPs.
