Preparation of nano/micro-scale column-like topography on PDMS surfaces via vapor deposition: Dependence on volatility solvents

► We prepared a column-like nano/micro-scale topography on the air plasma oxidized PDMS surfaces as a antifouling material. ► N-heptyl alcohol was mixed into the alkylsiloxane to regulate the scale and roughness of nano/micro-scale topography. ► Difference from dissolving silanes in paraffin oil in former research, TCOS is dissolved in dimethyl-silicone oil here.
