Polyamides have found a number of applications in the commercial sector. These materials belong to a large group of chemical compounds - polymers. The interest in these polymers is still growing as new materials can be formed through chemical functionalization or simply addition of different nanomaterials. Polyamides have many unique properties (e.g. chemical resistance, tensile and abrasion resistance, high thermal stability, non-flammability and high mechanical strength even after long periods of use), and compounds such as Nylon® or Kevlar® are leading components in the production of textiles, laboratory equipment, everyday objects or structural elements. Polyamides are used in automotive industry, aviation, and even as protective materials for the military. Several methods to synthesize polyamides exists to date. The most popular are reactions between carboxylic acid chlorides and amines, polycondensation of carboxylic acids with amines or polycondensation of amino acids. Especially spectacular is a reaction of pulling polyamide thread from the liquid-liquid interface known as the "nylon rope trick" experiment (https://www.youtube.com/watch?v=S6asCwVG8zU). Here, the reaction between 1,6-diaminohexane dissolved in the aqueous phase and adipoyl chloride being present in the immiscible with water organic phase is fast and spontaneous. In this work, we have proved that the synthesis of the polyamides at the liquid-liquid interface can be controlled using electrochemistry. In this respect, the electrochemically driven interfacial ion transfer or electrochemically modulated local pH changes are used to trigger the polycondensation within the locus defined by the liquid-liquid interface. The introduction to the electrified soft junction and its modification with polyamide is discussed in the concerned work.
