Inspired by natural species such as rose petals or Echeveria pulvinata leaves with both high water contact angle θw and high water adhesion (also called parahydrophobic), we have prepared poly(3,4-propylenedioxypyrrole) with branched alkyl chains on the 3-position by electropolymerization The grafting at the 3-position keeps the NH group free, which is an important condition to obtain nanofibers. Different lengths of branched alkyl chains are studied. Here, using extremely long branched alkyl chains (ProDOP-br-C10), it is possible to obtain extremely long and well defined nanofibers leading to porous surfaces (fiber mats) favoring the trapping of air between the surface and water droplets. Using a deposition charge of 200 mC cm-2, extremely high θw up to ~140° while water droplets placed on this surface remained stuck even for a sliding angle of 90°, revealing extremely strong adhesion. These materials could be used in the future in water harvesting systems. In the experiment, the researchers used many compounds, for example, Diethyl isobutylmalonate (cas: 10203-58-4Name: Diethyl isobutylmalonate).
Diethyl isobutylmalonate (cas: 10203-58-4) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Name: Diethyl isobutylmalonate
