Sustainable heterophasic ethylene-propylene copolymer composites with recycled aircraft graphite for antistatic packaging
Abstrak
Abstract Antistatic packaging prevents electrostatic discharge (ESD) damage, protecting electronic components during storage and transport, ensuring reliability in industries like electronics and aerospace. This study develops heterophasic ethylene-propylene copolymer (HEPC) composites reinforced with recycled aircraft graphite for antistatic applications. HEPC composites with 1, 5, and 10 wt% recycled graphite were prepared via twin-screw extrusion and injection molding. Morphological, thermal, rheological, mechanical, and electrical properties were analyzed. Adding 5 wt% graphite increased the elastic modulus by 21.3% and Shore D hardness by 6.1%. Electrical conductivity improved significantly, with a nine-order magnitude increase for 5 wt% graphite, enabling effective electrostatic dissipation. This sustainable approach enhances material performance while promoting circular economy practices by upcycling aerospace waste into high-value functional materials.
