摘要： A superhydrophobic graphite surface has been fabricated through two facile physical steps, peeling and ultrasonicating. Peeling yields micron-scale roughening, and thus a highly hydrophobic surface is obtained. Further ultrasonicating results in a superhydrophobic surface with nanostructure embedded in microstructure. The nanostructure leads to networklike pores on the superhydrophobic film and convective Ostwald ripening is observed. Owing to their distinct resistance to liquid imbibition, contact angle hysteresis on hydrophobic and superhydrophobic surfaces is fundamentally different. Moreover, the adhesive force on a superhydrophobic surface grows with the contact time, and such aging effect is absent on hydrophobic graphite surface. 出版者： American Institute of Physics 出版日期： 2012-03-19 出處： Applied physics letters, 2012-03, Vol.100 (12), p.121601-121601-4 資源來源： AIP Journals (American Institute of Physics) 版權： 2012 American Institute of Physics 識別號： ISSN: 0003-6951 識別號： EISSN: 1077-3118 識別號： DOI: 10.1063/1.3697831 識別號： CODEN: APPLAB
