Azopolymer film as an actuator for organizing multiwall carbon nanotubes
(Elsevier, 2017-01-25)
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 ...
Block copolymer concentration gradient and solvent effects on nanostructuring of thin epoxy coatings modified with epoxidized styrene-butadiene-styrene block copolymers
(ACS, 2012-01-27)
The gradient on block copolymer concentration through film thickness as well as the effects of casting solvents used on the nanostructuring of a thermosetting epoxy coating modified with an epoxidized poly(styrene-b-buta ...
Functional surfaces through the creation of adhesion and charged patterns on azopolymer surface relief gratings
(2019-03-29)
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 ...
Effect of CdSe nanoparticle addition on nanostructuring of PS-b-P4VP copolymer via solvent vapour exposure
(Elsevier, 2013-10-28)
The surface morphology of poly(styrene-b-4 vinyl pyridine) (PS-b-P4VP) diblock copolymer thin films
after solvent vapor annealing has been studied. Morphological features can be switched upon exposure
to vapors of a ...
Flexible polyurethane foams based on 100% renewably sourced polyols
(Elsevier, 2014-10-5)
Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably
sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of
flexible ...
High levels of molecular orientation of surface azo chromophores can be optically induced even in a wet biological environment
(2013-09-18)
We have developed polyelectrolyte multilayer bio-films containing azobenzene chromophores that enhance reversible photo-orientation
upon irradiation with linearly polarized light, to effect surface photoswitching of ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
Reversible optical storage properties of nanostructured epoxy-based thermosets modified with azobenzene units
(ACS, 2011-11-22)
Azo-containing polymers are of particular interest in the design of materials for applications in optical recording. The aim of this contribution was the synthesis and characterization of optically active epoxy-based ...
Hybrid materials based on azopolymer and sol-gel synthesized silver-containing titanium oxide nanoparticles with photoinduced birefringence
(The Royal Society of Chemistry, 2015-01-28)
The main goal of this work was the development of novel nanocomposite films with different optical
properties. A non-toxic water soluble azopolymer was modified with TiO2 nanoparticles and silver containing TiO2 nanoparticles. ...
Optically active multilayer films based on chitosan and an azopolymer
(2014-02-24)
The layer-by-layer technique has been widely adopted for the fabrication of nanostructures with tailored properties. In this work, photoactive multilayer films consisting of alternating layers of chitosan and an azopolymer ...
