With the aim of controlling the surface hydrophobicity and water adhesion, nanofibrous surfaces were prepared by electropolymerization of 3,4-ethylenedioxypyrrole (EDOP) and 3,4-propylenedioxypyrrole (ProDOP) derivatives having various alkyl chains (C3 to C17 ) grafted to a 3,4-alkylenedioxy bridge. Depending on whether an EDOP or a ProDOP was used, and the length of the alkyl chain, the surface properties of the resulting polymer were very different. The formation of nanofibrous surfaces was much more favored for ProDOP derivatives. The alkyl chain length has also a huge influence on the formation of nanofibers, and alkyl chains of intermediate length (C9 and C11 ) gave the best results. Apparent contact angles (θw ) of up to 150° were obtained, and the water adhesion properties were highly variable. This work is important for many applications in which the control of interaction forces with a medium is required, such as in oil-water separation membranes or water-harvesting systems.

通过电沉积烷基链取代的聚（3,4-乙撑二氧吡咯）和聚（3,4-丙二氧基吡咯）薄膜形成具有高水附着力的纳米纤维。

为了控制表面疏水性和水粘附性，通过使具有接枝到3的各种烷基链（C3至C17）的3,4-亚乙二氧基吡咯（EDOP）和3,4-亚丙二氧基吡咯（ProDOP）衍生物进行电聚合来制备纳米纤维表面。，4-亚烷基二氧基桥。根据使用的是EDOP还是ProDOP，以及烷基链的长度，所得聚合物的表面性能差异很大。ProDOP衍生物更倾向于形成纳米纤维表面。烷基链长对纳米纤维的形成也有很大的影响，而中等长度（C9和C11）的烷基链效果最好。获得了高达150°的表观接触角（θw），并且水粘附特性变化很大。
