face area and, therefore, protect the metal against harsh solution agents [6,7].The spin coating technique is broadly utilized in the production of polymer films. An additional polymer solution is placed on a substrate and is then typically rotated at 1000 to 5000 rpm for dispersing the fluid via the centrifugal force. Later, the solvent evaporation will thin the film. This technique is utilized in developing CDs and in electronic microchips [8]. A very small variation in the coating spin speed or in the solution concentration can cause significant changes in the final thickness. This way, film formation dynamics can be controlled and linked to the film final structure [9].Pure and extremely unreactive thermoplastic fluoropolymer called polyvinylidene difluoride or polyvinylidene fluoride (PVDF) is formed utilising vinylidene difluoride polymerization [10]. In addition, PVDF can be considered as one of the excellent polymers utilized in manufacturing micro and ultra-filtration membranes because of its good resistance against corrosion and wear, mechanical properties, and film-forming properties and thermal stability as well [11][12][13][14].HA is a bioactive and biocompatible substance that is available in nature and can interact with the surrounding bone [15]. The nanocomposite coatings are efficiently used to protect metals and alloys against corrosion. These coatings can be used as an alternative to poisonous and hazardous compounds. Nanocomposite coating is a solid multiphase substance containing one phase less than 100 nm in size. It works as a protective artificial layer located on the metal surface and repressing the reactions at the anode and cathode electrodes [16,17].
