Evaluation of graphite filler influence on the thermal performance of a PDMS heat exchanger
• Recycled graphite from industrial waste used as sustainable filler in PDMS composites. • Thermal conductivity increased by up to 93% at 30 mass% graphite via percolation effect. • Heat transfer coefficient improved by up to 1.9 times compared to pure PDMS. • Heat transfer efficiency reached 87% at 30% graphite loading under forced convection.
