    • Biodegradability and biocompatibility of copoly(butylene sebacate-co-terephthalate)s 

      Heidarzadeh, Nina; Mehdi Rafizadeh, Mehdi; Faramarz Afshar Taromi, Faramarz Afshar; Valle Mendoza, Luis Javier del; Franco García, María Lourdes; Puiggalí Bellalta, Jordi (2017-01-01)
      Article
      Accés obert
      In the present study poly (butylene sebacate-co-terephthalate)s having different compositions were synthesized with a high yield and a random distribution by thermal transesterification of poly (butylene sebacate) and poly ...

    • Hydrolytic and enzymatic degradation of biobased poly(4-hydroxybutyrate) films. Selective etching of spherulites 

      Keridou, Ina; Franco García, María Lourdes; Valle Mendoza, Luis Javier del; Martínez, Juan Carlos; Funk, Lutz; Turon Dols, Pau; Puiggalí Bellalta, Jordi (2021-01)
      Article
      Accés obert
      Hydrolytic degradation of poly(4-hydroxybutyrate) (P4HB) films has been studied considering media of different pH values (i.e., 3, 7 and 10) and temperatures (i.e., 37 and 55 °C). Enzymatic degradation has also been evaluated ...

    • Microstructural changes during degradation of biobased poly(4-hydroxybutyrate) sutures 

      Keridou, Ina; Franco García, María Lourdes; Valle Mendoza, Luis Javier del; Funk, Lutz; Turon, Pau; Puiggalí Bellalta, Jordi (Multidisciplinary Digital Publishing Institute (MDPI), 2020-09-01)
      Article
      Accés obert
      Fibers of poly(4-hydroxybutyrate) (P4HB) have been submitted to both hydrolytic and enzymatic degradation media in order to generate samples with different types and degrees of chain breakage. Random chain hydrolysis is ...

    • New poly(ester urea) derived from L-leucine: Electrospun scaffolds loaded with antibacterial drugs and enzymes 

      Díaz Andrade, Angélica María; Valle Mendoza, Luis Javier del; Tugushi, David; Katsarava, Ramaz; Puiggalí Bellalta, Jordi (Elsevier, 2015-01-01)
      Article
      Accés obert
      Electrospun scaffolds from an amino acid containing poly(ester urea) (PEU) were developed as promising materials in the biomedical field and specifically in tissue engineering applications. The selected poly(ester urea) ...

    • Poly(butylene azelate-co-butylene succinate) copolymers: Crystalline morphologies and degradation 

      Díaz Andrade, Angélica María; Franco García, María Lourdes; Estrany Coda, Francesc; Valle Mendoza, Luis Javier del; Puiggalí Bellalta, Jordi (2014-01)
      Article
      Accés restringit per política de l'editorial
      Random copolymers derived from 1,4-butanediol and two dicarboxylic units differing in the parity of the number of methylene groups and length of the polymethylene sequence (i.e. succinic and azelaic acids) were studied in ...

    • Preparation of random poly(butylene alkylate-co-terephthalate)s with different methylene group contents: crystallization and degradation kinetics 

      Heidarzadeh, Nina; Rafizadeh, Mehdi; Taromi, Faramarz Afshar; Puiggalí Bellalta, Jordi; Valle Mendoza, Luis Javier del; Franco García, María Lourdes (2017-10)
      Article
      Accés restringit per política de l'editorial
      Random copolyesters having 1,4-butanediol units were synthesized from a transesterification process between homopolymers constituted by aliphatic dicarboxylates (i.e. succinate, adipate or sebacate) and the aromatic ...

    • Tunable enzymatic biodegradation of poly(butylene succinate): biobased coatings and self-degradable films 

      Peñas, Mario Ivan; Criado Gonzalez, Miriam; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Flores, Araceli; Raquez, Jean-Marie; Mincheva, Rosica; Müller, Alejandro J.; Hernánez, Rebeca (Elsevier, 2023-05-01)
      Article
      Accés obert
      Biodegradation of polyesters driven by enzymes is considered as one of the most effective way of degradation of these materials, as a way to control plastics accumulation in the environment. In this study, we present two ...
