Polymer networks with dynamic bonds, also known as covalent adaptable networks (CANs) combine the superior mechanical properties and chemical resistance of thermosets with the ability to be reprocessed, a feat formerly ...

Versatile acrylate–epoxy hybrid formulations are becoming widespread in photo/thermal dual-processing scenarios, especially in 3D printing applications. Usually, parts are printed in a stereolithography or digital light ...

A new dual-curing scheme was developed for thiol-acrylate-epoxy mixtures. A photo-initiated latent catalytic system was used to carry out thiol-acrylate Michael addition at 35 °C (Stage 1) followed by thiol-epoxy click ...

In this work, the curing kinetics of a new ternary acrylate/epoxy/anhydride thermoset system which is used for dual-curing 3D-printing applications is studied. The first curing stage is an acrylate free-radical photopolymerization ...

Dual-curing processing is a method to prepare thermoset materials through two polymerization reactions carried out simultaneously or sequentially. In these processes, a firm understanding of reaction mechanisms enables ...

In this work, we have studied the preparation and characterization of a new family of thermosets based on off-stoichiometric diacid-epoxy formulations in the presence of 1-methylimidazole as initiator. Tri-glycidyl para-amino ...

3D-printed objects can greatly benefit from the introduction of molecular structure undergoing dynamic bond exchange [1] or the use dual-curing processing [2], leading to a significant enhancement of mechanical properties ...

Dual-curing thermosetting systems are recently being developed as an alternative to conventional curing systems due to their processing flexibility and the possibility of enhancing the properties of cured parts in single- ...

A new family of dual-curable poly(ß-hydroxyamine ether) thermosets based on amine-epoxy formulations has been prepared and characterized. Both curing stages consist in an epoxy-amine polycondensation, each having different ...
