  Stretchable Elastomer–Phase Change Composites for Passive Thermal Management in Wearable Electronics

  By M. Chennakesavulu, S. John Leon, P Joel Josephson, V.Parimala, DVSSSV Prasad, D. Priya Matharasi, Hirald Dwaraka Praveena, Sekar K, S. Sheik Mydeen

  Abstract: Elastomer-embedded phase change material (EPCM) composites are developed as stretchable, leakage-free, and electrically insulating thermal regulation layers for wearable electronics operating under stringent skin-safety requirements. The EPCM architecture comprises microencapsulated organic phase change materials (μPCM, 30–70 wt%) uniformly dispersed within soft elastomer matrices based on PDMS or SEBS-type thermoplastic elastomers, together with low loadings (1–8 wt%) of electrically insulating hexagonal boron nitride (h-BN) fillers to enhance lateral heat transport. Differential …

  Bio-inspired Thermo-responsive and Self-Healing Polymer–PCM Hybrids for Next-Generation Smart Textile Applications

  By Ishrat Meera Mirzana, Mohanrajhu N, Mohammed Sadiq Pachapuri, Arigela Sri Harsha, Hirald Dwaraka Praveena, Priyalatha. S, Nellore Manoj Kumar, G.S.V.Seshu Kumar, R. Ashok Kumar

  Abstract: The integration of phase change materials (PCMs) into flexible polymers represents a promising strategy for developing smart textiles with advanced thermal regulation and mechanical adaptability. However, the challenges of PCM leakage, poor mechanical strength, and durability under cyclic stress have limited their practical applications. In this study, we present a novel self-healing and elastic composite based on thermoplastic polyurethane (TPU) incorporating 30 wt% microencapsulated PCM (mPCM) and dynamic disulfide bonds …
