The core principle behind electrostatic removal is the manipulation of charged particles using an electric field. Hereâs a simplified breakdown of the process:
1. Charging the Particles: Nanoparticles can be charged through various methods, such as triboelectric charging or by suspending them in an electrically conductive medium. 2. Applying an Electric Field: Once charged, an electric field is applied. The charged nanoparticles move in response to the electric field, allowing for their separation or removal. 3. Collection or Removal: Depending on the application, these nanoparticles can be collected on a substrate or removed from the system entirely.
