Abstract

A light weight low power operated fabric based electroadhesive actuators were made with two dimensional hexagonal boron nitride (hBN) in PVdF-HFP polymer matrix as a dielectric and Cu/Ni fabric tape as electrodes for applications in robotics and exosuits. The properties of the dielectric layer were tuned for high load bearing capacity by inducing dangling joints in 2D hBN by the atmospheric ball milling as a factor of time. The electroadhesive actuator was optimized for a maximum load of 700 g for a DC voltage of 250 V, by changing the micro structures of 2D hBN with ball milling for different hours. The optimized load bearing capacity of the electroadhesive actuators obtained with 1 h ball milled 2D hBN incorporated PVdF-HFP matrix has been evidenced through structural and morphological studies.
