Cadmium oxide doped zinc oxide nanoparticles were synthesized by solution combustion technique. CdO-ZnO nanoparticles were reinforced into epoxy by ultrasonication technique. CdO-ZnO nano-particles are well known semiconducting materials which are found to exhibit excellent semiconducting behavior even at high frequencies. Hence it was introduced into epoxy to study the semiconducting nature of CdO-ZnO/epoxy composites. The polymer composites exhibited interesting phenomenon such as minimum heat losses at high frequencies indicating semi-conducting behaviour of the composites. The polymer composite was also analysed for its structural, thermal, optical and mechanical properties. The enhanced interaction of CdO-ZnO nanoparticles with epoxy has resulted in superior UV-shielding effeciency and mechanical properties. This paper mainly focusses upon the synthesis and development of CdO-ZnO/epoxy composites, the design and optimization of CdO-ZnO compositions, the mechanical toughening and failure mechanism, transport mechanism of charge carriers, conductivity relaxation, ionic polarization and prospects of CdO-ZnO/epoxy composites in various fields.
