  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 …

  Mechanical and Physicochemical Characteristics of Nano-Hydroxyapatite Polymer Composites

  By J. Lurdhumary, Ashwin Sailesh, DVSSSV Prasad, N. Krishnamoorthy, P. Sivabalan, S. Suresh, S. Philip Raja, G. Nixon Samuel Vijayakumar, K. Uma

  Abstract: This study focuses on the development and characterization of nano-hydroxyapatite (nHAp)-reinforced poly (lactic acid) (PLA) composites for biomedical applications. The composites, prepared with varying nHAp content (5–25 wt%), were evaluated for their mechanical and physicochemical properties, including tensile strength, Young’s modulus, elongation at break, thermal stability, hydrophilicity, and crystallinity. Results revealed that tensile strength increased significantly with the incorporation of nHAp, reaching a peak of 62 MPa at 15 wt%, …
