Effect of coactive influence of LDHs and PNCC on thermal and mechanical properties of epoxy resin

ABSTRACT

The nanofiller improve the properties of the pristine polymer resins to the great extent. In present findings, the preparation of nanocomposites (epoxy/PNCC/LDHs) was done by the ‘Slurry-compounding method’. Precipitated nano-calcium carbonate (PNCC) were mixed with Layer double hydroxides (LDHs) in varying ratio and added to epoxy resin with constant stirring at room temperature. The degree of distribution of the nanofiller and the kind of polymeric nanocomposites formed was observed by Wide-angle X-ray Diffraction, and Scanning Electron Microscopy. The thermal and mechanical properties of epoxy nanocomposites were characterised by Thermogravimetric analysis and Universal Testing Machine, respectively. However, harmonisation and coactive influence of PNCC with LDHs showed a better effect on the mechanical and thermal properties of epoxy resin and offers superior mechanical and thermal properties as compared to pristine epoxy resin and two-component ( Epoxy/PNCC) nanocomposites.
