Abstract
Extremely low sliding angle, 0.15±0.03° with 20 μl distilled water droplet, was measured on diamond-like carbon–polydimethylsiloxane hybrid (DLC–PDMS-h) coating (advancing and receding contact angles for water were θ A/ θ R=101°/99°). Diamond-like carbon–polymer hybrid (DLC–p-h) coatings were prepared with filtered pulsed arc discharge (FPAD) method using a graphite–polymer cathode. The polymers used in the hybrid coatings were polydimethylsiloxane (PDMS) and polytetrafluoroethylene (PTFE). Contact and sliding angles of these hydro- and oleophobic (i.e., water and oil repellent) new coatings were measured with water and oil (hexadecane and cooking oil).
