Conductors particles

If a conduc tor particle and a nonconduc tor particle are just separated from contac t with a charged plate, the conductor particle will be repelled by the charged plate and the nonconducting particle will be neither repelled nor attracted by it. 

Balachandran [23] analyzed the role of electrostatic forces in the adhesion between sohd particles and surfaces. According to the available information this role is not completely clear, the results are contradictory. Electrostatic forces can be significant in the case of polymer and semi-conductor particles. These forces have four main types Coulomb, image charge, space charge and dipole forces.
