Enhancing the Properties of Polymer Composites by Stable Dispersion and Magnetic Alignment of Graphene Nanoplatelets

Polymer composites with graphene fillers is prepared. Excellent dispersion of high concentration graphene in composites is achieved. The fabricated foam sensor is electrically conductive, highly sensitive and exhibit sensing characteristics at low pressure <1kPa. Sensors are calibrated, and mechanical properties is studied. Composite materials with graphene orientation are prepared using static magnetic field. Nearly 50% of THz radiation is absorbed by aligned graphene composite films. The mechanism of graphene orientation under magnetic field, the degree of alignment is studied mathematically and by SANS technique. This work opens avenues for graphene inks/paints, sensing using composite materials and composites for future technologies.
