Novel approach to fabricate polycarbonate antibacterial superhydrophobic surfaces

A novel approach to fabricate a stable polycarbonate (PC) surface with superhydrophobicity and antibacterial properties obtained by use the phase separation and solvent/non-solvent selected method without any use to surface chemical modification materials, with high chemical stability. At the same time a systematic study of dependence surface morphology on the acetone/DMF solvent mixture treatment. In medical devices, the bacterial attachment onto the surface of polymers such as a PC is influenced by the physicochemical properties of the polymers, including surface roughness and hydrophobicity. The resulting surfaces demonstrated that the water CA of the PC surface was 154 ± 2° with excellent inhibition percentage of two bacteria. FESEM showed that the surface structure comprised branches or petals outside the ‘plant seabeds’ with a hierarchical micro-/nano-binary formation, in addition to related AgNps with a rough surface. In order to test the stability and properties of the PC surfaces, Pseudomonas aeruginosa and Acinetobacter baumannii suspensions in ‘Amide Organic’ was poured above the surface and allowed to settle on top of the surface for several minutes, then, the Anti-adhesive effect of colonies bacteria was evaluated and the results showed the very small percentage of bacteria was adhesive on surfaces.
