A hybrid epoxy composite was synthesized by adding halloysite nanotubes (HNTs) to an epoxy matrix toughened by an acrylic triblock copolymer (MAM). The morphology generated was composed of spherical MAM domains with sizes in the range of hundreds of

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. dibutylamine, DBA) or prima

Epoxy vitrimers were synthesized employing stoichiometric amounts of diglycidyl ether of bisphenol A (DGEBA), sebacic acid (20% eq.) and an n-alkylamine, either octylamine (OA), dodecylamine (DA) or hexadecylamine (HA) (80% eq.). Apart from the chemi

Alkyl chains of β-hydroxyesters synthesized by the capping of terminal epoxy groups of diglycidylether of bisphenol A (DGEBA) with palmitic (C16), stearic (C18), or behenic (C22) fatty acids self-assemble forming a crystalline phase. Above a particu

Commercial triblock copolymers with a poly(butyl acrylate) (PBuA) central block joined to two poly(methyl methacrylate) (PMMA) end blocks (denoted as MAM) or to two random copolymers end blocks based on MMA and N,N′-dimethylacrylamide (DMA) (denote

Stable dispersions of silver nanoparticles (Ag NPs) were synthesized employing glycerol as both a solvent and reducing agent, and 3-aminopropyl trimethoxysilane (APTMS) as a stabilizer. Average sizes varied between 13 and 55 nm, depending on the mola

Polymerization-induced nanostructuration combined with crystallization-driven self-assembly was used to generate complex nanostructures in an epoxy network. A PE-b-PEO block copolymer (Mn = 1400; 50 wt% PEO), was dispersed in diglycidylether of bisph

Vitrimers are covalently crosslinked polymers that behave as conventional thermosets below the glass transition temperature (Tg) but can flow above a particular temperature, Tv > Tg, by bond exchange reactions. In epoxy vitrimers, transesterification
