Development of Advanced Thermoplastic Elastomeric Mat and Its Study on Thermal Performance of Wireless Charging System

This study aimed to develop a thermally conductive TPE mat and assess its performance in comparison to an existing antiskid rubber mat, specifically evaluating its impact on wireless charger efficiency. Moreover, morphological and thermal analyses were conducted to establish a correlation between the material behaviours of the new and current thermally conductive antiskid mats. The process of developing the thermally conductive TPE involved utilizing a two-roll mill followed by compression moulding to achieve a 2D sheet shape. Notably, the thermally conductive mat demonstrated a consistent enhancement in charging efficiency over the conventional antiskid mat. To examine the thermal characteristics, thermal characterization techniques including DSC and TGA were employed for both the existing and newly developed mats. FTIR spectroscopy was also utilized to confirm the presence of organic functional groups within the mat. The morphological analysis of the fillers used to enhance thermal conductivity was conducted through SEM. The resulting insights contributed to understanding the structural changes that contributed to the improved thermal performance. Subsequently, the developed thermally conductive mat sheet was evaluated in the context of wireless charger performance. The findings and implications of these evaluations were thoroughly discussed. In summary, this research successfully developed a thermally conductive TPE mat and highlighted its superior performance in terms of wireless charging efficiency compared to the traditional antiskid mat. Thermal and morphological analyses provided deeper insights into the material properties, while the evaluation of the mat's impact on wireless charger performance demonstrated its practical significance.
