Resum

In this paper, we report the modification of polypirrole (PPy) with dopaminated hyaluronic acid (HADA). This design improves PPy adhesion onto stretchable materials such as poly(dimethylsiloxane) (PDMS) allowing the formation of conducting films on this kind of very flexible, hydrophobic materials. The results revealed that described PPy modification allows to obtain stable PPy:HADA nano–suspension able to cast films directly on PDMS. The comparison of PPy:HADA films with conventional PPy and other modified PPy shows that the modification improved the strength of the films under tension stress and their water resistance. Moreover, the modification proposed does not affect significantly the conductivity of the PPy films. The resulting properties of the material make it especially suitable for bio–integrated device applications, where a biocompatible material with stable electrical behaviour under deformation and water media is needed.
