Ball milling was used to prepare nanocrystalline TiO2, GO and PVDF-HFP/TiO2/GO nanocomposite, and the effects of milling hours on phase transformation and crystal size wasinvestigated. The films were made using the doctor blade method. XRD, SEM, FTIR spectra were used to characterize the prepared samples. The dielectric constant values were calculated for different milling hour. A lightweight, low-power film is described here for controlling the engagement in a mobile cleaning device. Electrostatic adhesion between thin electrode sheets covered with a dielectric substance underpins the film. The load bearing is influenced by the GO to TiO2 wt.%. A portable device has been fabricated based on the concept of electroadhesion.
