The electroadhesive properties of polymer particles 5 to 30 μm in diameter have been assessed by the values of their individual charges after tearing off, and by the force of their adhesion to a solid surface. It has been established that the electroadhesion properties of polymer particles are largely determined by the donor-acceptor interaction between the main functional groups of polymers and the solid surface. The electroadhesive properties of particles in contact with the surface of a photoconductor have been found to be affected by exposure to light. The spectral dependence of the adhesion force of particles and the variation in the distribution of the torn-off particles with regard to a charge sign under the effect of exposure to light are related to a variation in the density of the double electric layer at their interface with the solid surface. The results obtained are interpreted on the basis of notions on the preponderant role of the forces of electrostatic nature, which are attributable to the effect of the double electric layer at the interface, in the adhesion interaction of the particles with the solid surface.
