AB - Similar to Casimir force, nanofibers have a potential that attracts water  molecules, while the porosity of the nanofiber mat produces a repelling  force. Wetting property of a nanofiber mat is a result of combination of the  forces and gravity. A new concept, the geometric potential or the  boundary-induced force, is introduced to elucidate the basic property of  wetting. Various nanofiber mats with different fiber morphologies are  fabricated by the bubble electrospinning. The paper concludes that  superhydrophobic properties of nanofiber mat depends upon mainly fiber  morphology and porous structure of the mat, hydrophilic properties of ZnO  nanorods will not affect the water contact angle much.
