Conductive elastomers with tuneable properties for smart wearable electronics.

Descrizione del progetto

Polimeri flessibili per applicazioni tessili intelligenti

I polimeri organici con proprietà conduttive stanno attirando sempre più interesse grazie al loro basso costo di sintesi e alla facilità di manipolazione. I tessuti intelligenti sono tra le applicazioni più interessanti e futuristiche di questi materiali. Tuttavia, gli attuali polimeri conduttori sono troppo fragili per essere usati nei tessuti. Il progetto TEXTHIOL, finanziato nell’ambito del programma Marie Skłodowska-Curie, mira a creare un polimero elastomerico conduttivo con proprietà materiali avanzate che può essere applicato direttamente come substrato per tessuti intelligenti. Per realizzare il substrato polimerico il progetto sfrutterà la reazione nucleofila di click chemistry tiol-ino tra un alchino e un tiolo.

Obiettivo

Organic conductive polymers are gaining increased interest each day due to their broad applications, low cost and ease of manipulation. Their potential to develop new products that will transform the daily lives of people in Europe and around the world is significant. Among the application areas with the highest potential, smart textiles provide one of the most futuristic and innovative potential products. At present, a conducting polymeric material that can be use directly as textile does not exist primarily a consequence of the poor (brittle) materials properties of conducting polymers. Any such products are created by coating of the conductive material onto the textile or tissue. However the ability to use polymers to create wearable electronics has transformative potential to become a disruptive technology. This proposal aims to create a conductive polymer with elastomeric properties such that it has enhanced materials properties and can therefore be applied directly as scaffold for smart textile creation. To make the polymeric scaffold, the nucleophilic thiol-yne “click” reaction between an activated alkyne and thiol will be used. This pathway will enable retention of the electrical conductivity while presenting the possibility to tune the mechanical properties by choosing the stereochemistry (E/Z) of the unsaturated bond that is formed. Moreover, the elastomeric nature of the resultant materials, presents a unique opportunity to create conductive elastomers that can be easily applied to wearable electronics: able to record electrical signals such as heartbeats or muscular contractions. The project is going to combining the organic synthesis and click chemistry expertise of Mantione with that of conducting polymer synthesis and characterization of Prof. Hadziioannou. The planned secondment is aiming to allied to the expertise of Prof. Malliaras (Cambridge, UK) in wearable electronics: biotest the materials and practically create the textile.
