ELECTROADHESIVE PROPERTIES OF POLYMER PARTICLES IN CONTACT WITH THE PHOTOCONDUCTOR SURFACE

The electroadhesive properties of polymer particles 5 to 30 mum in dia meter have been assessed by the values of their individual charges aft er tearing off, and by the force of their adhesion to a solid surface. It has been established that the electroadhesion properties of polyme r particles are largely determined by the donor-acceptor interaction b etween the main functional groups of polymers and the solid surface. T he electroadhesive properties of particles in contact with the surface of a photoconductor have been found to be affected by exposure to lig ht. The spectral dependence of the adhesion force of particles and the variation in the distribution of the torn-off particles with regard t o 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 interf ace with the solid surface. The results obtained are interpreted on th e basis of notions on the preponderant role of the forces of electrost atic nature, which are attributable to the effect of the double electr ic layer at the interface, in the adhesion interaction of the particle s with the solid surface.
