Optimized curing and coating of smart paints for surface temperature measurements

초록

Excess thermal energy can cause significant damage to the mechanical parts of various systems. Temperature sensors can measure and control the temperature in these systems to prevent such damage. However, the applications of existing temperature sensors are limited by their shape as it limits their ability to attach to different surfaces. Consequently, it is challenging to measure the temperature of curved surfaces. In this study, we propose a smart paint that can measure the temperature of curved surfaces to address the above issues. The smart paint fabrication method must be optimized because the resistance characteristics of these paints differ according to the manufacturing conditions. In this study, a curing process was used to manufacture the smart paint; the optimal curing temperature and curing time were determined experimentally. Furthermore, a coating solution was applied to increase the surface stability of the fabricated paint. The coating was applied using a spin coater at a specific rotation time and speed. We also determined the optimal coating conditions. The coating was confirmed to increase the surface stability of the smart paint.
