Effect of Adhesive Layer on Electromechanical Response Behavior of Macro Fiber Composites

Abstract

Abstract: The effect of the bonding layer parameters on the electromechanical response behavior of macro fiber composites (MFC) was analyzed, from the perspective of mechanical and electrical coupling of functional materials. It is found that reducing the thickness and increasing the dielectric constant of the adhesive layer are beneficial to alleviate the dielectric mismatch phenomenon of MFC via the finite element simulation, increasing the effective electric field load and obtain high-voltage electrical performance. Reducing its elastic modulus can improve the deformation ability of MFC. The MFC were fabricated, the actuating and sensing performance were characterized. The experimental results are consistent with the simulation data. Reducing the thickness and elastic modulus of the adhesive layer, increasing its dielectric constant can increase its tip displacement and output voltage of MFC, and improve the actuating and sensing performance. The research provides guidance for the design of MFC for actuating and sensing.
