Effect of chemical modifications on the electronic structure of poly(3-hexylthiophene)
The widespread use of poly(3-hexylthiophene) (P3HT) in the active layers of organic solar cells indicates that it possesses chemical stability and solubility suitable for such an application. However, it would be desirable ...
Modelling polymers with side chains: MEH-PPV and P3HT
Modelling polymers with side chains is always a challenge once the degrees of freedom are very high. In this study, we present a successful methodology to model poly[2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylenevinylene] ...
Interface morphology snapshots of vertically segregated thin films of semiconducting polymer/polystyrene blends
(Elsevier B.V., 2007-04-05)
We present atomic force microscopic images of the interphase morphology of vertically segregated thin films spin coated from two-component mixtures of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV) ...
Self-healable polymer networks based on the cross-linking of epoxidised soybean oil by an aqueous citric acid solution
(Royal Society Of Chemistry, 2013-09-09)
Epoxidised soybean oil (ESO) was cross-linked with an aqueous citric acid (CA) solution without the addition of any other catalyst or solvent. Completely bio-based polymer networks were generated. The initial system was ...
3D Nanostructured Conjugated Polymers for Optical Applications
(Wiley VCH Verlag, 2015-11)
The self assembly of block-copolymers into the gyroid morphology is replicated into 3D nanostructured conjugated polymers. Voided styrenic gyroidal networks are used as scaffolds for the electrodeposition of two ...
Polymer Brushes Here, There and Everywhere: Recent Advances in Their Practical Applications and Emerging Opportunities in Multiple Research Fields
Bottom-up surface processing with well-defined polymeric structures becomes increasingly important in many current technologies. Polymer brushes, that is, assemblies of macromolecules tethered at one end to a substrate, ...
Influence of colorants on the degradation and stabilization of polymers.

Tracking high molecular weight polymer interdiffusion on a SERS-based platform
(John Wiley & Sons Ltd, 2016-11-18)
We describe the implementation of an experimental setup based on Surface Enhanced Raman Spectroscopy (SERS) to investigate polymer interdiffusion. Ultra-thin bilayer films of deuterated polystyrene (dPS) and polystyrene ...
