    Polymeric Hybrid Systems Engineered with Multiple-Stage Energy Absorption for Temperature Control

    By G. Sunil, Selvaraju, T.S. Senthil, N. Saikumari, S. Nooray Sashmi, Sivakumar A., Zakir Hussain, J. Sharmila, Shailendra Kumar Bohidar

    Abstract: Polymer–composite based phase change systems offer an effective strategy for adaptive thermal management; however, most existing systems exhibit single-stage latent heat transitions, limiting their applicability in environments with fluctuating thermal loads. In this study, a thermoplastic polyurethane (TPU) polymer matrix was reinforced with two microencapsulated paraffin-based phase change materials (PCM-A and PCM-B) to achieve multi-level latent heat storage behavior. The fabricated TPU/PCM-A10–B20 polymer–composite demonstrated two distinct endothermic transitions at approximately …

    Solar-Responsive Photo-Thermal Polymer Composites with Carbon Nanostructures for On-Demand Water Purification

    By M. Dhanalakshmi, Weiwei Jiang, S. UmaMaheswara Reddy, S. Arun Kumar, Deobarat Kumar Chandan, T. Venkatamuni, S. Nooray Sashmi, Yagya Dutta Dwivedi, Arun Chokkalingam

    Abstract: The development of solar-responsive polymer nanocomposites offers a sustainable pathway for water purification. In this work, polyvinyl alcohol (PVA) films reinforced with graphene nanoplatelets (GNPs) and multi-walled carbon nanotubes (MWCNTs) were fabricated and systematically investigated for their mechanical, thermal, viscoelastic, and thermal transport properties. Neat PVA displayed moderate tensile strength (~38 MPa) and high elongation (~165%), whereas 1.0 wt% nanofiller loading enhanced tensile strength to ~52 MPa and modulus to …

    Electroactive Graphene–Polymer Nanocomposites for Self-Sustaining and Multifunctional Flexible Devices

    By J. Lurdhumary, Suguna B. Rao, S. Nooray Sashmi, Praveen Vundrajavarapu, V.G. Pratheep, G. Nixon Samuel Vijayakumar, V. Pandyaraj, K. Manimekalai, Zakir Hussain

    Abstract: Graphene–reinforced polymer–composites were developed and systematically investigated to explore their multifunctionality in flexible electronic applications. The study specifically aims to correlate graphene-induced structure–property–function relationships with electroactive performance and self-sustaining behaviour in flexible devices. The hybridization of electroactive polymers—polyaniline (PANI), poly(3,4-ethylenedioxythiophene): polystyrene sulphonate (PEDOT:PSS), and polyvinylidene fluoride (PVDF)—with graphene nanoplatelets enabled simultaneous enhancement of electroactivity, energy-harvesting, and sensing functionalities. Morphological studies confirmed uniform graphene dispersion at 5 wt.% loading, forming continuous …
