Analysis of the non-ideal crosslinking process in thiol-X “click” thermosets
(Elsevier, 2024-04-13)
Article
Open AccessThiol-click reactions are widely used in the preparation of thermosets. The network build-up process follows step-wise polymerization behavior, which is commonly analyzed assuming ideal step-wise behavior using well- known ... -
Biobased imine vitrimers obtained by photo and thermal curing procedures-promising materials for 3D printing
(American Chemical Society (ACS), 2024-03-14)
Article
Open AccessImine-based vitrimers were prepared from synthesized diimine-dimethacrylate monomer derived from biobased vanillin. First, a methacrylate derivative starting from vanillin was synthesized. The diimine derivative was ... -
Harnessing disulfide and transesterification bond exchange reactions for recyclable and reprocessable 3D-printed vitrimers
(2024-02-01)
Article
Open AccessTwo new vitrimeric materials have been studied for potential additive manufacturing applications such as 3D- printing. A monomer containing disulfide bonds and ß-hydroxyesters was easily synthesized from two low- cost and ... -
Eugenol-based dual-cured materials with multiple dynamic exchangeable bonds
(Elsevier, 2024-02-21)
Article
Open AccessIn the present work, the preparation of sustainable thermosets has been approached simultaneously from three different points of view: a) the use of bio-based monomers chemically modified through green methodologies, b) ... -
Easily recycled thiol-ene elastomers with controlled creep
(Elsevier, 2024-03)
Article
Open AccessStarting from in-house synthesized allylic monomers containing dynamic disulfide (S–S) bonds, a set of vitrimeric thiol-ene elastomers were prepared and characterized with respect to their viscoelastic and tensile properties. ... -
Preparation of poly(thiourethane) networks by using a novel acidic organocatalyst. Evaluation of their vitrimer-like behavior
(2023-02)
Article
Restricted access - publisher's policyIn this work, a novel acidic catalyst, isopropyl methane sulfonate, has been tested for the preparation of a series of poly(thiourethane) thermosets (PTU)s. The advantage of this compound is that in addition to being free ... -
Dual-cured thermosets based on eugenol derivatives and thiol chemistry
(Elsevier, 2023-11-22)
Article
Restricted access - publisher's policyThis paper aims to increase sustainability in thermosetting polymeric fields using bio-based monomers and environmentally friendly processing technologies based on dual-curing. Eugenol has been transformed into acrylate ... -
Critical analysis of the thermal stability of transesterification vitrimers for 3D-printing applications based on digital light processing
(2024-04-01)
Article
Open Access3D-printable vitrimers processed by digital light processing (DLP) have been recently developed, based on the transesterification reaction of ß-hydroxyester structures from mono- and diacrylate monomers employed in the ... -
The use of lanthanide triflates in the preparation of poly(thiourethane) covalent adaptable networks
(Elsevier, 2023-09-22)
Article
Open AccessCovalent adaptable networks (CANs) are new polymeric materials with the mechanical properties of thermosets and the possibility of being recycled like thermoplastics. Poly(thiourethane) networks have demonstrated vitrimeric-like ... -
Structural design of CANs with fine-tunable relaxation properties: a theoretical framework based on network structure and kinetics modeling
(American Chemical Society, 2023-06-23)
Article
Open AccessIn this work, we present a model capable of reproducing the stress relaxation dynamics of a wide range of relaxation processes in covalent adaptable networks (CANs) produced by stepwise polymerization. The proposed model ... -
Recyclable dual-curing thiol-isocyanate-epoxy vitrimers with sequential relaxation profiles
(Elsevier, 2023-09-11)
Article
Open AccessTwo series of poly(thiourethane)s-poly(thiol-epoxy) hybrids were prepared from dual-curing, stoichiometric thiol:isocyanate:epoxy mixtures. 1-methylimidazole (MI) was used as initiator for the thiol-isocyanate and thiol-epoxy ... -
Adhesive properties of thiol-acrylate-epoxy composites obtained by dual-curing procedures
(Elsevier, 2022-01)
Article
Open AccessComposite materials were prepared using a thiol-acrylate-epoxy dual-curing system filled with Boron Nitride (BN) agglomerates. The adhesive properties obtained with two different acrylate ratios (ra) were tested to ...
