Abstract

Ultraviolet (UV) curing systems have garnered significant attention and scholarly focus due to their remarkable ability to facilitate rapid curing processes while simultaneously exhibiting low energy consumption characteristics, which are increasingly pertinent in contemporary manufacturing and environmental sustainability discussions. The aim of this study is investigating the multifaceted role that polyaniline in UV-curable epoxy acrylate coatings. Both polyaniline and epoxy acrylate resin were synthesized through established chemical processes and subsequently characterized using a range of analytical techniques. To assess the impact of polyaniline on the epoxy acrylate resin, varying percentages of polyaniline, specifically at concentrations of 1%, 3%, and 5%, were systematically incorporated into the epoxy acrylate resin matrix to evaluate their effects on the resultant material properties. A detailed analysis of the morphological characteristics of the prepared nanocomposites revealed a well-distributed and appropriate dispersion of polyaniline particles throughout the polymer matrix, which is crucial for achieving optimal performance in the final product. Thermal stability of the sample containing 3% polyaniline exhibited a remarkable enhancement, being twice as high when compared to the sample that contained only 1% polyaniline, thus highlighting the significance of polyaniline concentration on thermal properties. Furthermore, it was observed that the electrical conductivity of the sample incorporating 3% polyaniline experienced a substantial increase, quantified at an impressive factor of 4.25 times greater than that of the sample with a lower concentration of 1%, underscoring the enhanced electrical performance attributable to the optimized incorporation of polyaniline within the epoxy acrylate matrix.
