类荷叶结构聚全氟乙丙烯的超疏水性
Superhydrophobicity of Lotus-leaf-like Fluorinated Ethylene Propylene Copolymer Surface
摘要
Abstract
Superhydrophobic fluorinated ethylene propylene (FEP) copolymer surface with lotus-leaf-like structure was prepared by thermoforming FEP powder at the condition of 0.3 N/cm2, 280 ℃ and - O. 1 MPa vacuum on the polydimethylsiloxane(PDMS) templates, which replicated the lotus leaf surface. The SEM results indicate that the FEP surface shows great similar lotus-leaf-like structures with superhydrophobic, corresponding water contact angle and tilt angle are ( 168 ± 1 )° andd 2°, respectively. The superhydrophobic lotusleaf-like FEP surface also exhibits good stability in water, acohol, acid and alkaline solution after duration of 10 h immersion. Furthermore, once the hydrophobicity of FEP surface decreased, it is recoverable via an immersion process in piranha solution for 10 min. Differential scanning calorimetry( DSC ) results indicate the mass loss of the PDMS templates is very low, which means it can be used repeatedly during the thermoforming process. Therefore, the methods combine the very good acid resistant, alkaline resistant and corrosion resistant of the FEP with lotus-leaf-like structure to fabrication of superhydropobic surface may be applied in preparation of anti-adhension and serf-cleaning vessels, etc.关键词
