Pentacene and PANI are important semiconductors in the organic electronics
field. An alternative synthesis to obtained semiconductors materials is
proposed in this work with the development of Pentacene/PANI/AgNps
membrane for electronic devices applications. In this work, pentacene was
synthetized and reported in previous works, where the synthesis was performed
in two reactions, Diels-Adler cycloaddition of 6,13-pentacenequinone followed
by 6,13-pentacenequinone reduction to pentacene, employing LiAlH4 as
reducing agent. PANI was obtained by the oxidation of aniline using ammonium
persulfate in an acidified (HCl) with stable phase at pH 7. AgNps was synthetized
by ultrasound assisted synthesis at room temperature with a distribution size
between 10-20 nm. The final membrane was easily development by sol-gel
method where Pentacene/PANI/Ag Nps were distributed in a PVA matrix
through of HCl reducing agent and glycine as complexing agent in a short
reaction time. Ag nanoparticles were added to improve the behavior of the
polymers. Membrane was studied by Fourier Transform Infrared Spectroscopy
(FTIR), X-Ray Diffraction (XRD), thermogravimetric analysis (TGA) and ultravioletvisible
spectrophotometry (UV-VIS). The characteristics obtained in the
membrane make a semiconductor accessible in different electronic
applications.
