    New acylhydrazone vitrimeric-type materials have been studied. These materials can be efficiently relaxed, without the addition of an external catalyst, through an exchange process that has been confirmed as imine metathesis, ...
  • Preparation and Characterization of a Series of Self-Healable Bio-Based Poly(thiourethane) Vitrimer-like Materials 

    Guerrero Ruiz, Federico; Ramis Juan, Xavier; De la Flor López, Silvia; Serra Albet, Maria Àngels (Multidisciplinary Digital Publishing Institute (MDPI), 2023-03-01)
    Article
    Open Access
    A series of poly(thiourethanes) (PTUs) from biobased monomers have been synthesized. Limonene and squalene were transformed into polyfunctional thiols by thiol-ene reaction with thioacetic acid and further saponification. ...
  • Thiol-Ene Networks with Tunable Dynamicity for Covalent Adaptation 

    Konuray, Ali Osman; Moradi, Sasan; Roig, Adrià; Fernández Francos, Xavier; Ramis Juan, Xavier (American Chemical Society (ACS), 2022-01-01)
    Article
    Open Access
    To be fully recyclable, covalent adaptable networks must ultimately be able to overcome all topological restrictions and flow. By using a statistically based method, it was shown that the extent of stress relaxation in ...
  • Optimization and testing of hybrid 3D printing vitrimer resins 

    Casado Gómez, Jaime; Konuray, Ali Osman; Benet, Gerard; Fernández Francos, Xavier; Morancho Llena, José María; Ramis Juan, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-24)
    Article
    Open Access
    The quality of photocure-based 3D printing greatly depends on the properties of the photoresin. There are still many challenges to be overcome at the material level before such additive manufacturing methods dominate the ...
  • Vitrimeric Epoxy-Amine Polyimine Networks Based on a Renewable Vanillin Derivative 

    Roig Gibert, Adriá; Hidalgo, Pere; Ramis Juan, Xavier; De la Flor López, Silvia; Serra Albet, Maria Àngels (American Chemical Society (ACS), 2022-01-01)
    Article
    Open Access
    A series of bio-based polyimine vitrimers was obtained and characterized. A diimine-diglycidyl monomer (DIDG) was synthesized by condensing vanillin with 4,4'-oxydianiline (ODA) and further glycidylation with epichlorohydrin. ...
