The effects of temperature, humidity, and kinds of nanofiller on electrical and structural properties of advanced polymer nanocomposites was the focus of this study. A special consideration was given to the analysis of conductivity retention as well as the morphological behavior of the conductive fillers like CNTs, graphene, and AgNPs. Under the climate mapping of thermal-humidity characteristics, conductivity was observed to lower with elevated temperatures and relative humidity and hence the influence of stress in material degradation. Based on the results of the evaluation of the fillers, the composites with AgNPs presented the highest recovery efficiency of over 95%, proving that were capable of operations under cyclic stress conditions. From the experimental results, it was also possible to observe the electricity’s dependance with temperature, as the resistance decreased when temperature was increased, as expected for a thermally activated conduction, involving a percolative transport mechanism. SEM imaging also confirmed the microstructure where it showed that CNTs had a fibrous structure while AgNPs were uniformly distributed at the nanoscale; properties that enhance the electron transport characteristics of the composite. The incorporation of these fillers enhanced the electrical aspect of the composite without affecting the structural pliability and flexibility. The discovery provides valuable insights into the dispersion of nanofiller and the formulation of the composite system with improved thermal-electrical stability, which applies to the development of next generation flexible electronics, sensors, and energy devices. This study lays the groundwork for the relationship between the morphology of the material and its functional capability, which would improve the development of long-lasting nanocomposite systems.

Keywords: Polymer nanocomposites, Carbon nanotubes (CNTs), Silver nanoparticles (AgNPs), Conductivity retention, Thermal stability, Morphological analysis.
