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.

摘要

纳米填料在很大程度上改善了原始聚合物树脂的性能。在目前的研究结果中，纳米复合材料（环氧树脂/ PNCC / LDHs）的制备是通过“浆料混合法”完成的。将沉淀的纳米碳酸钙（PNCC）与不同比例的双层氢氧化物（LDHs）混合，并在室温下不断搅拌下将其添加到环氧树脂中。通过广角X射线衍射和扫描电子显微镜观察纳米填料的分布程度和形成的聚合物纳米复合材料的种类。分别通过热重分析和通用试验机对环氧纳米复合材料的热性能和力学性能进行了表征。然而，
