| 中文摘要 | high contact angle hysteresis on polyelectrolyte multilayers (pems) ion-paired with hydrophobic perfluorooctanoate anions is reported. both the bilayer number of pems and the ionic strength of deposition solutions have significant influence on contact angle hysteresis: higher ionic strength and greater bilayer number cause increased contact angle hysteresis values. the hysteresis values of similar to 100 degrees were observed on smooth pems and pinning of the receding contact line on hydrophilic defects is implicated as the cause of hysteresis. surface roughness can be used to further tune the contact angle hysteresis on the pems. a surface with extremely high contact angle hysteresis of 156 was fabricated when a pem was deposited on a rough substrate coated with submicrometer scale silica spheres. it was demonstrated that this extremely high value of contact angle hysteresis resulted from the penetration of water into the rough asperities on the substrate. the same substrate hydrophobized by chemical vapor deposition of 1h,1h,2h,2h-perfluorooctyltriethoxysilane exhibits high advancing contact angle and low hysteresis. |
