Synergistic effect of impure/pure graphene oxide and TiO2 fillers on the dielectric properties of poly (vinylidene fluoride- hexafluoropropylene) for electroadhesive high load bearing applications
Poly (vinylidene fluoride- hexafluoroproylene) PVDF-HFP has been employed as a host polymer because of its strong chemical resistance, mechanical and dielectric properties and low cost. However, further changes employing other polymers, nanomaterials, additives and fillers to improve the properties of the host polymers are of significant interest. TiO2 has gained a lot of attention because of its high k dielectric and photo catalytic capabilities. Graphene oxide (GO) has received a lot of attention because of its larger mechanical strength, dielectric behavior and other qualities. Using the doctor blade coating process, varied amounts of TiO2 and GO were successfully integrated into PVDF-HFP to form composite films. The XRD result reveals that TiO2/GO has been successfully incorporated into the PVDF-HFP polymer matrix, while FTIR, SEM experiments have demonstrated the effectiveness of TiO2/GO fillers on PVDF-HFP film. AC impedance spectroscopy reveals the dielectric behavior and resistivity of polymer nanocomposite film. The film has been tested for its loading bearing capacity during electroadhesion with different applied voltages. The maximum load bearing capacity based on electroadhesion has been estimated.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
