  Thermally Regulated Polymer-PCM Composites for Efficient Solar Energy Harvesting and Storage

  By Dhivakar Poosapadi, J. Sofia Priya Dharshini, P. Booma Devi, Vikash Kumar, Pankaj Kumar Ray, Shiv Kumar Ray, Binu Sukumar, Nellore Manoj Kumar, Yesudhas Abisha

  Abstract: This study investigates the development of high-performance; shape-stabilized polymer composites infused with phase change materials (PCMs) for thermal energy storage in solar energy applications. Polyethylene glycol (PEG-6000) was employed as the core PCM due to its high latent heat and suitable melting point, while high-density polyethylene (HDPE) served as the supporting polymer matrix to provide structural stability. One of the primary limitations of PEG-based PCMs is their inherently low thermal …

  Sustainable Epoxy Composites Enhanced by Cellulose Nanocrystals for Structural and Thermal Applications

  By P. Saravana Kumar, Bipin Kumar Srivastava, Dhivakar Poosapadi, Sasikumar G, Mayilvani K, Nellore Manoj Kumar, S. Arunprasad, Binu Sukumar, K. S. Babulal

  Abstract: This study presents the advancement and behaviour analysis of sustainable nanocomposites reinforced with cellulose nanocrystals (CNCs), a biodegradable and high-aspect-ratio nanofiller derived from microcrystalline cellulose. CNCs were incorporated into a bisphenol-A-based epoxy matrix at varying concentrations (0, 1, 3, 5, and 7 wt%) to assess their influence on mechanical, thermal, and viscoelastic properties. The tensile strength of the composites increased significantly, from 45 MPa for neat epoxy to 65 MPa …
