Abstract

Cold plasma treatment leads to the electrical charging of liquid organic (polydimethylsiloxane) surfaces. Water droplets placed on the surface of cold radiofrequency plasma treated polydimethylsiloxane oil were used as probes enabling the estimation of the specific surface charge supplied by plasma to polydimethylsiloxane. The specific surface charge was also established independently by the electrostatic pendulum. The surface charge density was estimated as σ≅0.5÷3μC/m2.
