Development of a nanocomposite chemiresistor sensor based on Π-conjugated azo polymer and graphene blend for detection of dissolved oxygen
(2018-10-15)
The present paper describes the electrochemical impedance activity of a hybrid film with graphene and poly(azo-Bismarck Brown Y) as the chemiresistor material. This nanocomposite film exhibits interesting properties based ...
Synergistic effect of reduced graphene oxide/azo-polymer layers on electrochemical performance and application as nonenzymatic chemiresistor sensors for detecting superoxide anion radicals
(2019-11-01)
The present paper describes a nonenzymatic chemiresistor sensor based on an azo-polymer and reduced graphene oxide (rGO) as a resistive platform for superoxide radical detection. The sensorial platform was prepared on ...
SYNTHESIS AND CHARACTERIZATION OF THERMALLY STABLE NOVEL POLYMERS CONTAINING PHENYLTHIOUREA, AZO AND SULFONE GROUPS IN THE BACKBONE

Analyses of surface relief gratings inscription in epoxy-azo linear and crosslinked polymers
(John Wiley & Sons Inc, 2017-07-31)
This work evaluates the inscription of surface relief gratings (SRG) in a series of epoxy-azo prepolymers and networks, both based on the same azo chromophore. Variables such as matrix structure (thermoplastic/thermoset), ...
Liquid crystalline side chain methacrylic azo containing polymers
(2009)
This paper describes the synthesis and characterisation of methacrylic liquid crystalline side chain polymer containing azo group, with (PM6OAn) and without (PM6An) hydroxyl group. The characterisation was done by using a ...

O presente trabalho de pesquisa tem por objetivo demonstrar os resultados obtidos com o estudo e desenvolvimento de um nanocompósito formado a partir de um azo polímero funcionalizado com grafeno como fotossensibilizador ...
Understanding the Performance of a Nanocomposite Based on a Conjugated Azo-Polymer and Reduced Graphene Oxide with Photoelectrically Switchable Properties by Analyzing the Potential Profile during Photocurrent Generation
(2020-01-01)
This work describes the photoelectrochemical properties of devices coated with poly(azo-Bismarck Brown R) and the nanocomposite poly(azo-Bismarck Brown R)/reduced graphene oxide. Chronoamperometric methods with pulsed light ...
Surface relief gratings inscription in linear and crosslinked azo modified epoxy-isocyanate polymers
(Wiley, 2015-02)
This work analyses the SRG forming ability of a linear and a crosslinked polymer, both based on the same azo chromophore (Disperse Red 19, DR19) and diisocyanate (4,4´-metilen-bis(cyclohexyl isocyanate), DI) with similar ...
Photobleaching effect in azo-dye containing epoxy resin films: The potentiality of carbon nanotubes as azo-dye dispensers
(Institute of Physics Publishing, 2015-04)
Azo-dye molecules may suffer from bleaching under certain illumination conditions. When this photoinduced process occurs, it generates an irreversible effect that is characterized by the loss of absorption of the dye ...
Methylated DNA impedimetric immunosensor based on azo-polymer-AuNPs dots and 5-methylcytosine antibody using dissolved oxygen as a redox probe
(2022-03-01)
The present work describes the development of an electrochemical immunosensor for the direct determination of methylated DNA using dissolved oxygen as the redox probe. The oxygen-sensitive response is possible due to the ...
