“…A4 is distinguished by its enhanced dielectric performance, which results from the incorporation of carbon quantum dots. The high surface area and conductive properties of carbon quantum dots lead to an increase in permittivity, which in turn has a beneficial effect [26]. The dielectric performance is enhanced because to this enhanced polarization ability in reaction to an electric field.…”

This study investigates the degradation and performance characteristics of a composite made of carbon quantum particles (CQD), bamboo fiber, and aluminized glass fiber. It also looks at the thermal aging analysis of polymeric thermal materials. Carefully extracted from sugarcane bagasse, a sustainable byproduct, are the CQD particles. The fabrication process involves compression molding, ensuring that the composite conforms to ASTM standards during characterization. Thermal aging experiments are conducted in a hot air oven at a consistent temperature of 50 degrees Celsius, spanning durations of 120, 240, and 360 days. Finding out how thermal aging affects the composite's mechanical qualities, dielectric characteristics, fatigue resistance, and thermal conductivity is the main goal. Observations reveal a certain level of decline in all thermal aged specimens when compared to non-aged counterparts, where the non-aged specimens consistently exhibit superior values in all properties. However, the decline values are deemed negligible and manageable due to their low magnitudes. These reduced drop in values highlight the ways that carbon quantum particles, stacked bamboo fibers, and aluminized glass fiber reinforce one another. The minimal reduction in properties demonstrates the composite material's ability to withstand high-temperature environments without compromising its overall performance. This study contributes valuable insights into the durability and reliability of polymeric thermal materials. The implications extend to diverse applications, including insulation, electrical components, and structural reinforcements even at high temperature areas.
