Abstract
The present invention relates to fibers exhibiting a water contact angle of above 150° and water contact angle hysteresis of below 15°, methods of producing the same, and applications thereof. The present invention further relates to superhydrophobic fiber mats, methods of producing the same, and applications thereof.
Claims74
A non coated fiber comprising a copolymer, wherein a mat of said fibers exhibits a water contact angle of above 150° and water contact angle hysteresis of below 15°, wherein said copolymer comprises a component having a silicon structure and/or wherein said copolymer is fluorinated.
A superhydrophobic mat of non coated fibers comprising a copolymer wherein said mat exhibits a water contact angle of above 150° and water contact angle hysteresis of below 15°, wherein said copolymer comprises a component having a silicon structure and/or wherein said copolymer is fluorinated.
A method for preparing a non coated fiber or fibers, the method comprising the step of electrospinning a solution comprising a copolymer, wherein said copolymer comprises a component having a silicon structure and/or wherein said copolymer is fluorinated, wherein a mat of said fibers exhibits a water contact angle of above 150° and water contact angle hysteresis of below 15°.
