Synthesis of 2D graphene and boron nitride utilizing physical defects and chemical functionalization and their applications to vibration damper and electromechanical composite actuator

Abstract

The damping materials were developed by using h-BN and polyurethane composites. It was tested that the damping performance by FRF measurement using an aluminum beam that damping materials coated on the surface. In addition, electro-active composite actuators based on graphene reinforced Nafion composite electrolytes were developed and their electro-chemo-mechanical properties and actuation performances were investigated. On the other hand, the defect engineering method is applied to the quantum dot synthesis. Furthermore, the edge-hydroxylated functionalization was employed to enhance the intracellular uptake of the BNQDs in cells for bioimaging.
