Abstract

Artificial leather has been developed for decades as a key element in apparel design due to its thermal insulation function. However, with the changes of public preferences, the focus has shifted from functionality to a greater awareness of aesthetics. Therefore, an area for innovative artificial leather with high thermal conductivity as the cover of smart electronic devices is emerging. This leather will enable both special functions and aesthetical appearance to catch the attention of the public. It can also be utilized for spring–summer clothing in following fashion trends. Exploring new markets also means breaking away from the traditional seasonal cycle. However, the only current method for improving thermal conductivity (k) is to reduce its thickness, which sacrifices durability and appearance. Therefore, in this research, a novel solution is established, in which an additive with high k (TCA), aluminum oxide (Al2O3), is added into the resin layer of artificial leather at appropriate ratios to improve its thermal conductivity. Currently, the two most adopted production methods are used to develop a prototype without generating any extra cost. The results indicate that the modified leather has a high k, has an aesthetically pleasing appearance and a soft and cool hand feeling. The k of HTCAL is 48.3% higher than that of normal leather. In addition, in wear trials, a larger temperature difference is found between the skin and the HTCAL, indicating that HTCAL has a good heat transfer. Finally, a prototype for an iPhone case is developed and it is established that the method can be used for mass production to realize benefits.
