Optical storage properties in cast films of an azopolymer
(ABM, ABC, ABPol, 2003-06)
In this paper we discuss the properties of optically induced birefringence in DR19-MDI cast films that may be used in optical storage applications. The selection of DR19-MDI cast films was based on a comparative study of ...
Azopolymer film as an actuator for organizing multiwall carbon nanotubes
(Elsevier Science, 2017-01)
In this work we show the feasibility of using an azopolymer as an actuator to induce nano- and microscale movements controlled with light from the far field. We study azopolymers and their interaction with multi-walled ...
Functional surfaces through the creation of adhesion and charged patterns on azopolymer surface relief gratings
(Elsevier Science, 2019-04)
We show that an azopolymer can be used to create a supramolecular architecture in a parallel process with patterned surface properties. By illuminating with an interference pattern, we created adhesion and charge patterns ...
Increase of SRG modulation depth in azopolymers-nanoparticles hybrid materials
(Elsevier Science, 2021-05)
Thin films of azopolymer-nanoparticles hybrid materials were fabricated with poly[1-[4-(3-carboxy-4-hydroxyphenylazo) benzenesulfonamido]-1,2-ethanediyl] (PAZO) and different concentrations of Ag and AgAu nanoparticles ...
Running holograms in azopolymer films
(2013-04-01)
We report investigations on running holograms recorded in an azopolymer film made of a poly(methyl methacrylate) matrix doped with Disperse Red 1. Two-wave mixing experiments were carried out in the symmetrical transmission ...
Molecular engineering strategies to control photo-induced birefringence and surface-relief gratings on layer-by-layer films from an azopolymer
(Elsevier B.V., 2004-04-01)
The interactions governing adsorption of layer-by-layer (LBL) films from an azopolymer, PS-119(R), and poly(allylamine hydrochloride) (PAH) have been controlled by modifying the pH of the solutions used to form the films. ...

Development of a molecularly imprinted polymer for uric acid sensing based on a conductive azopolymer: Unusual approaches using electrochemical impedance/capacitance spectroscopy without a soluble redox probe
(2021-09-15)
In the present study, we report the use of an electrochemical sensor for uric acid using a molecularly imprinted polymer (MIP) as a molecular recognition platform. The MIP was based on an azopolymer electropolymerized in ...

Polyurethane-epoxy based azopolymers: Influence of chemical structure over photoinduced birefringence
(Elsevier Science, 2012-07)
A comparative study of the influence of the competitive reactions that can take place in epoxy-isocyanate based azo systems over optical behavior was developed. Diverse disperse red 19 (DR 19) azo urethane oligomers (PUs) ...
