A facile method was used to create both of the super-hydrophilic and super-hydrophobic properties on polyester/cellulose fabric blend. The fabric was exposed to air corona discharge treatment without any extra chemical modification. The static contact angle of 0^∘ and 167^∘ was indicated for super-hydrophilic and super-hydrophobic samples, respectively. The decrease of intensity of active functional groups and the increase of roughness with a nano-scale pattern presented a super-hydrophobic surface that confirmed by ATR-FTIR, AFM and FESEM analysis. This is while the increase of intensity of the active functional groups and the surface roughness with a micro-scale pattern was shown for the super-hydrophilic sample. The wettability tests show the enhancement of hydrophobic and hydrophilic properties for 300 W–10 min and 800 W–10 min corona discharge treated samples, respectively. Therefore, there is a critical point of the corona discharge process that enables it to create hydrophobic and/or hydrophilic properties on the substrates.

一种简便的方法被用来在聚酯/纤维素织物混合物上同时具有超亲水和超疏水特性。该织物未经空气化学电晕放电处理。静态接触角为^0∘和^167∘分别用于超亲水和超疏水样品。ATR-FTIR，AFM和FESEM分析证实了活性官能团强度的降低和纳米级图案粗糙度的增加，呈现出超疏水的表面。在此期间，对于超亲水性样品，活性官能团的强度增加，并且表面粗糙度呈现微尺度图案。润湿性测试表明，分别在300 W–10分钟和800 W–10分钟的电晕放电处理的样品中，疏水性和亲水性得到增强。因此，电晕放电过程的关键点使其能够在基板上产生疏水和/或亲水特性。
