Sequential dual curing by selective Michael addition and free radical polymerization of acetoacetate-acrylate-methacrylate mixtures
(2018-01)
Article.
Accés obert
Article.
Accés obert
A new family of poly(keto ester)-poly(methacrylate) thermosets based on off-stoichiometric acetoacetate-acrylate/methacrylate formulations has been prepared and characterized. The first stage of curing is a self-limiting ...
Highly exfoliated nanostructure in trifunctional epoxy/clay nanocomposites using boron trifluoride as initiator
(Wiley, 2014-03-15)
Article.
Accés obert
Article.

Epoxy/clay nanocomposites based upon a trifunctional epoxy resin, triglycidyl p-amino phenol (TGAP), have been prepared by intercalating an initiator of cationic homopolymerization, a boron trifluoride monoethylamine ...
New understanding of the shape-memory response in thiol-epoxy click systems: towards controlling the recovery process
(Springer, 2017-02-01)
Article.
Accés obert
Article.
Accés obert
Our research group has recently found excellent shape-memory response in “thiol-epoxy” thermosets obtained with click-chemistry. In this study, we use their well-designed, homogeneous and tailorable network structures to ...
Characterization of sequential dual-curing of thiol-acrylate-epoxy systems with controlled thermal properties
(Elsevier, 2019-03-01)
Article.
Accés obert
Article.
Accés obert
In this work, a novel sequential dual-curing system based on thiol-acrylate-epoxy formulations is developed and characterized. Both reaction stages are thermally activated and sequentially relies on difference in the ...
Thermal curing of an epoxy-anhydride system modified with hyperbranched poly(ethylene imine)s with different terminal groups
(Springer, 2017-01)
Article.
Accés obert
Article.
Accés obert
New hyperbranched polymers (HBP) have been
synthesized by reaction of a poly(ethylene imine) with phenyl and t-butyl isocyanates. These HBPs have been characterized by 1H-NMR (nuclear magnetic resonance of
hydrogen) and ...
New epoxy composite thermosets with enhanced thermal conductivity and high Tg obtained by cationic homopolymerization
(2018-06-01)
Article.
Accés obert
Article.
Accés obert
Thermal dissipation is a critical aspect for the performance and lifetime of electronic devices. In this work, novel composites based on a cycloaliphatic epoxy matrix and BN fillers, obtained by cationic curing of mixtures ...
Structural analysis of the curing of epoxy thermosets crosslinked with hyperbranched poly(ethyleneimine)s
(2015-09-01)
Article.
Accés obert
Article.
Accés obert
The network build-up process during curing of an epoxy resin using a hyperbranched poly(ethyleneimine) as crosslinking agent has been studied from a theoretical and experimental point of view. A systematic analysis taking ...
The application of thermal analysis to the study of epoxy–clay nanocomposites
(Springer, 2016-08)
Article.
Accés obert
Article.
Accés obert
The development of polymer layered silicate (PLS) nanocomposites goes back over 20 years now, and yet they still have not achieved their full potential. A principal reason for this is the difficulty of obtaining a truly ...
State of the art in dual-curing acrylate systems
(2018-02-12)
Article.
Accés obert
Article.
Accés obert
Acrylate chemistry has found widespread use in dual-curing systems over the years. Acrylates are cheap, easily handled and versatile monomers that can undergo facile chain-wise or step-wise polymerization reactions that ...
