Improved load bearing performance of electroadhesive tapes with Hexagonal boron nitride/Barium titanate composite in Poly (vinylidene fluoride co-hexafluoropropylene)

The electroadhesive actuators were assembled using Cu–Ni fabric electrodes and hBN-incorporated BaTiO 3 dielectric composite materials in PVdF-HFP matrix as the electroadhesive tape. The electroadhesive performance of the above tape was tested using a DC–DC booster circuit for different weight percentages of ball-milled hBN into the dielectric composite. The load bearing capacity was found to be multiplied several fold from 100 to 950 gm for voltage of 250 V. The dielectric behavior of as-prepared electroadhesive tape made using the PVdF-HFP matrix was analyzed using impedance analyzer. XRD and SEM studies were performed to justify the behavior of the powder composites embedded in PVdF-HFP matrix as electroadhesive tapes.
