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), ...
Diffusion and hydrolysis effects during water aging on an epoxy-anhydride system
(Elsevier, 2018-07)
Hydrothermal aging of an epoxy-anhydride network has been studied by means of gravimetric analysis, Fourier transform infrared spectroscopy (FTIR) and modulated differential scanning calorimetry (MDSC). The long-term aging ...
An artificial neural network (ANN) model for predicting water absorption of nanoclay-epoxy composites
(Scientific Research Publishing Inc., 2019-07)
Glass fiber reinforced epoxy (GFRE) composite materials are prone to suffer from water absorption due to their heterogeneous structure. The main process governing water absorption is diffusion of water molecules through ...
Nanoribbons with semicrystalline core dispersed in a visible-light photopolymerized epoxy network
(Elsevier, 2014-11-29)
It has been well documented that self-assembly of block copolymers (BCP) in selective solvents, where the core-forming block is a crystallizable polymer, results in micelle structures with exceptional aggregation morphologies ...
Epoxies modified by palmitic acid: From hot-melt adhesives to plasticized networks
(Wiley VCH Verlag, 2005-05)
Reactions taking place in a homogeneous solution of an epoxy monomer based on the diglycidyl ether of bisphenol A (DGEBA) and palmitic acid (PA), in the presence of benzyldimethylamine (BDMA), were investigated using ...
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) ...
Monitoring of visible light photopolymerization of an epoxy/dimethacrylate hybrid system by Raman and near-infrared spectroscopies
(Elsevier, 2013-08-11)
Hybrid systems formulated with epoxy and methacrylate monomers at mass fraction either 50:50 or 75:25 were studied. The individual monomer conversions during photopolymerization with visible light were monitored by Raman ...

A simple strategy to generate light-responsive azobenzene-containing epoxy networks
(Elsevier, 2013-09-20)
Azobenzene containing epoxy networks are a class of photosensitive materials characterized by high thermal, optical and mechanical stability, promising for reversible optical storage applications. Here, we propose an ...
