Super-Hydrophobic Surface Manufacture on Pyrolytic Carbon via Electrostatic Spinning Method

Abstract:

To reduce the adhesion of blood cells to the pyrolytic carbon surface of heart valve prosthesis, pyrolytic carbon is utilized as the foundation material for the realization of surface super-hydrophobicity. In this process, 10% PVP in concentration is used as the raw material and netted fiber film is textured on the surface of pyrolytic carbon material via electrostatic spinning method at the voltage of 12KV. The experiment results show that the contact angle of the pyrolytic carbon surface amounts to 154o after electrostatic spinning treatment and many porous structures are formed on the fiber film. The conclusion is thus reached that fiber film featured by super-hydrophobicity is attributable to the inability to fill the fiber meshes of liquid drops, which retain the air beneath and then give rise to this super-hydrophobic feature.
