Using principles of electrochemistry, one can create polymers with switchable hydrophilic and hydrophobic characteristics.
After successfully performing the electropolymerization of Pyrrole onto a glass substrate, followed by the electrochemical oxidation of the Pyrrole (Ppy) film (dark area at the centre of the square), this is what happened when a 5 μL droplet of water is placed onto the Ppy film.
My first experiment relating to materials chemistry was hands down the most exciting and interesting experiment I have performed so far in my undergraduate studies. Who knew I would get so excited to see a bead of water resting on a surface?
