Materials with desirable properties, including good deformability, high thermal conductivity, and superior electromagnetic interference (EMI) shielding, are in demand the modern electronics sector. In order to overcome fundamental heat transport EMI shielding limitations soft elastic materials, liquid metal (LM) is dispersed randomly self-healing polyurethane (SPU) produce composites conductivity excellent properties preserving softness deformability of precursor. Furthermore, stretching-induced filler alignment method utilized elongate align LM SPU matrix along draw direction, resulting simultaneous enhancement in-plane effectiveness (SE) composites. LM/SPU 80 wt% loading show as 12.8 W·m-1·K-1 total SE 72 dB, respectively, at ratio 3. Excellent facilitates its stretching which makes phonon transfer easier allows for multiple reflections absorption waves, greatly enhances shielding. addition, prepared healing properties. Therefore, this study provides a promising strategy integrating multifunctional into single composite system application flexible electronics.
