 This paper presents a new method for creating multifunctional materials with improved electricity generation and EMI shielding capabilities. By using origami folding techniques, the authors were able to create flexible multilayered phase change films, PCFs. These films have been shown to increase the light thermal electrical conversion efficiency by up to 11.3% while also improving the generated electricity by up to 27.3%. Additionally, the EMI shielding capability of these films was found to range from 39.2 to 71.9 dB, making them ideal for a variety of applications. This research demonstrates the potential of origami-based materials for multifunctionality and could lead to more efficient and reliable electronics.
