ELECTRIC FIELD ALIGNMENT OF MULTI-WALLED CARBON NANOTUBES THROUGH CURING OF AN EPOXY MATRIX
(Nanofun-Poly European Network of Excellence, 2012-09)
The electrical alignment of multi-walled carbon nanotubes (MWCNT) in an epoxy resin was studied through curing using electrical measurements and optical microscopy. The epoxy system was composed by diglycidyl ether of ...
Direct relationships between volume variations at macro and nanoscale in epoxy systems. PALS/PVT measurements
(Elsevier, 2004-12)
The free volume in epoxy systems fully cured with aminic hardeners having different chemical structures was studied by means of positron annihilation lifetimes spectroscopy. The results are compared with those obtained ...
Controlling Nanodomain Morphology of Epoxy Thermosets Modified with Reactive Amine-Containing Epoxidized Poly(styrene-b-isoprene-b-styrene) Block Copolymer
(American Chemical Society, 2014-10)
Controlling nanodomain morphology of nanostructured epoxy thermosets is critical to modulate the mechanical properties of the cross-linked matrix. In this contribution, we demonstrate that this can be achieved by using a ...
Microscale evaluation of epoxy matrix composites containing thermoplastic healing agent
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2023)
Morphology profiles obtained by reaction-induced phase separation in epoxy/polysulfone/poly(ether imide) systems
(Wiley, 2005-02-15)
The reaction-induced phase separation in epoxy/aromatic diamine formulations simultaneously modified with two immiscible thermoplastics (TPs), poly(ether imide) (PEI) and polysulfone (PSF), has been studied. The epoxy ...
Visible-light photopolymerization of epoxy-terminated poly(dimethylsiloxane) blends: Influence of the cycloaliphatic monomer content on the curing behavior and network properties
(Pergamon-Elsevier Science Ltd, 2020-07)
Siloxane-based networks were obtained by photoinitiated cationic ring-opening polymerization of mixtures composed of two different siloxane monomers: poly(dimethylsiloxane) diglycidyl ether (PDMS-DGE) and bis [2(3,4-epoxy ...
Epoxy vitrimers with a covalently bonded tertiary amine as catalyst of the transesterification reaction
(Pergamon-Elsevier Science Ltd, 2019-02)
Tertiary amines are one of the typical catalysts used to accelerate transesterification reactions in epoxy vitrimers. Instead of adding a tertiary amine (e.g. tributylamine, TBA) to the initial formulation, secondary (e.g. ...
Properties of epoxy networks derived from the reaction of diglycidyl ether of bisphenol a with polyhedral oligomeric silsesquioxanes bearing OH-functionalized organic substituants
(John Wiley & Sons Inc, 2003-07-01)
A polyhedral oligomeric silsesquioxane (POSS), consisting mainly of a mixture of octahedra, nonahedra, and decahedra with bulky and flexible organic sub-stituents, with three secondary hydroxyls per organic group, was used ...
Nanostructured epoxies based on the self-assembly of block copolymers: A new miscible block that can be tailored to different epoxy formulations
(American Chemical Society, 2007-02)
Nanostructured thermosets may be obtained by the self-assembly of amphiphilic block copolymers (BCP) in a reactive solvent and fixation of the resulting morphologies by the cross-linking reaction. Nanostructuration requires ...
Generation of large and locally aligned wormlike micelles in block copolymer/epoxy blends
(Elsevier, 2014-11-07)
A dispersion of wormlike micelles, empirically found in some block copolymer (BCP) / epoxy blends, has been reported to produce a significant toughening of epoxy networks. In this study, a rationale procedure to generate ...
