    The wettability of poly (dimethylsiloxane) (PDMS) coating on plasma-treated glass was studied at room temperature using polar and non-polar liquids. The wettability was investigated regarding the liquids' surface tensions (STs), dielectric constants (DCs) and solubility parameters (SPs). For polar liquids
