Superhydrophobic Films of Electrospun Binary Structured Fibers |
| 초록 |
Some surfaces found in nature have self-cleaning properties. Such surfaces have the unusual wetting phenomena of superhydrophobicity with water contact angle greater than 150˚. Water droplets on the surface readily roll off when the contact angle hysteresis is negligible and subsequently, surface dust and debris can be removed easily. In the present work, we demonstrate a simple method for fabricating fibrous structures of dual scales in micrometers and nanometers on fibers by electrospinning bidisperse silica particles in polymer solution. Also, porous silica nanofibers were produce by electrospinning silica nanoparticles and polymeric particles of which the latter was used as a sacrificial template. The electrospun binary structured fibers were hydrophobically modified with fluorinated silane coupling agents. Superhydrophobic surfaces with low sliding angle were thereby successfully prepared. |
