| Abstract [eng] |
nanocomposite for anti-corrosive steel protection and to comprehensively evaluate the mechanical properties of this nanocomposite. Two methods were trialled to incorporate LDH particles into epoxy resin. In the first approach, a Mg-Al/NO3 LDH slurry in water was utilised. A nine-step particle washing procedure was employed, gradually replacing water with ethanol, acetone, and finally xylene. LDH particles in xylene were added to bisphenol A epoxy in specific volume fractions and mixed with a high shear stirrer. Subsequently, an isophorone diamine hardener was added and epoxy/LDH nanocomposites were obtained. Dog-bone shaped specimens were prepared for characterisation and mechanical testing. As an alternative method for particle incorporation into epoxy resin, the insertion of dried LDH powder into the resin was used. Epoxy/LDH samples prepared in this way were also thoroughly examined. Comparative analysis of all sample groups revealed that the mechanical properties of the new nanocomposites, if reduced, were only slightly so, and in some cases, even improved. |
