Main results

Within this project are obtaind and patterned novel azo-PI, with checked structures, high glass transition temperatures and thermostability, ability to be processed in the form of films with high flexibility and resistivity, photochromic behavior, adequate morphological features, good adhesion with the tested metals and good dielectric properties, resistance to certain solvents, improved piezoelectric properties induced by the anisotropy of the morphology, succesfuly tested as alternative substrates for flexible/stretchable electronic devices and sensors applications.
