When the control voltage is constant or zero, the ball is "glued" to the wall of the cavity due to the electrostatic forces.
It can be observed that as contact time was above 250 min, the adsorption capacity for AYGG followed the order of LZ-1 > LZ-O > LZ-2, indicating synergistic effect of pore size, specific surface area, hydrogen bond, [pi]-[pi] and electrostatic force were responsible for the adsorption of AYGG.
DC] voltage difference sets up an electrostatic force of attraction and pulls the movable plate toward the fixed plate, thereby decreasing the distance of separation and increasing the capacitance.
