A pH-triggered polymer degradation or drug delivery system by light-mediated Cis/Trans isomerization of o-hydroxy cinnamates
(2021-01-01)
Article
Open AccessA new methodology for the pH-triggered degradation of polymers or for therelease of drugs under visible light irradiation based on the cyclization ofortho-hydroxy-cinnamates (oHC) to coumarins is described. The keyoHCstructural ... -
Amyloid-like fibrils from a diphenylalanine capped with an aromatic fluorenyl
(2018-11-19)
Article
Open AccessThe self-assembly behavior of a diphenylalanine amphiphile blocked at the C-terminus with a 9-fluorenylmethyl ester and stabilized at the N-terminus with a trifluoroacetate (TFA) anion, TFA·FF-OFm, has been examined. At ... -
Biphasic polylactide/polyamide 6,10 blends: Influence of composition on polyamide structure and polyester crystallization
(Elsevier, 2020-08-12)
Article
Open AccessBlends with different ratios of polylactide and polyamide 6,10 (PA610) have been prepared by melt-mixing using a Brabender mixer equipment. Previously, a rheologically modified polylactide (PLAREx) was obtained through ... -
Electrospun scaffolds for wound healing applications from poly(4-hydroxybutyrate): A biobased and biodegradable linear polymer with high elastomeric properties
(Wiley, 2022-01-05)
Article
Open AccessElectrospun scaffolds of the biodegradable and biocompatible poly-4-hydroxybutyrate (P4HB) polyester have been prepared using horizontal and vertical set-up configurations of electrospinning. Specifically, it has been ... -
Hydrolytic and enzymatic degradation of biobased poly(4-hydroxybutyrate) films. Selective etching of spherulites
(2021-01)
Article
Open AccessHydrolytic 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 ... -
Isothermal crystallization kinetics of poly(4-hydroxybutyrate) biopolymer
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
Article
Open AccessThermal properties and crystallization kinetics of poly(4-hydroxybutyrate) (P4HB) have been studied. The polymer shows the typical complex melting behavior associated to different lamellar populations. Annealing processes ... -
Microstructural changes during degradation of biobased poly(4-hydroxybutyrate) sutures
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-09-01)
Article
Open AccessFibers 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 ... -
Non-isothermal crystallization kinetics of poly(4-hydroxybutyrate) biopolymer
(2019-08-05)
Article
Open AccessThe non-isothermal crystallization of the biodegradable poly(4-hydroxybutyrate) (P4HB) has been studied by means of differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). In the first case, Avrami, ... -
Scaffolds with tunable properties constituted by electrospun nanofibers of polyglycolide and poly(e-caprolactone)
(2018-01-01)
Article
Open AccessElectrospun scaffolds constituted by different mixtures of two biodegradable polyesters are prepared. Specifically, materials with well differentiated properties can be derived from the blending of hydrophilic polyglycolide ... -
Study on crystallinity, properties and degradability of poly-4-hidroxybutyrate and related polyesters
(Universitat Politècnica de Catalunya, 2021-04-14)
Doctoral thesis
Open AccessIn the last decades, polymeric biomaterials, due to their advanced physical and mechanical properties, have been used in a vast variety of surgical and pharmaceutical applications. In this thesis, a study on crystallinity, ...
