Candidate Polyurethanes Based on Castor Oil (Ricinus communis), with Polycaprolactone Diol and Chitosan Additions, for Use in Biomedical Application

Uscategui, Yomaira L.; Diaz, Luis E.; Gómez-Tejedor, José-Antonio; Vallés Lluch, Ana; Vilariño, Guillermo; Serrano, María-Antonia; Valero, Manuel F. (MDPI AG, 2019-01-10)

[EN] Polyurethanes are widely used in the development of medical devices due to their biocompatibility, degradability, non-toxicity and chemical versatility. Polyurethanes were obtained from polyols derived from castor ...
Hydrolytic stability and biocompatibility on smooth muscle cells of polyethylene glycol-polycaprolactone-based polyurethanes

Morales-Gonzalez, Maria; Arévalo-Alquichire, Said; Diaz, Luis E.; Sans-Tresserras, Juan Ángel; Vilariño, Guillermo; Gómez-Tejedor, José-Antonio; Valero, Manuel F. (Cambridge University Press (Materials Research Society), 2020-12-14)

[EN] Interactions between smooth muscle cells (SMCs) and biomaterials must not result in phenotype changes as this may generate uncontrolled multiplication processes and occlusions in vascular grafts. The aim of this study ...
Influence of Polyol/Crosslinker Blend Composition on Phase Separation and Thermo-Mechanical Properties of Polyurethane Thin Films

Arevalo-Alquichire, Said; Morales-Gonzalez, Maria; Navas-Gomez, Kelly; Diaz, Luis E.; Gómez-Tejedor, José-Antonio; Serrano, María-Antonia; Valero, Manuel F. (MDPI AG, 2020-03)

[EN] Polyurethanes (PUs) from Polyethylene glycol (PEG) and polycaprolactone diol (PCL) and a crosslinker, Pentaerythritol (PE), were synthetized with isophorone diisocyanate (IPDI). In this study, we investigated the ...
Polyurethane-based bioadhesive synthesized from polyols derived from castor oil (Ricinus communis) and low concentration of chitosan

Uscátegui, Yomaira L.; Arevalo-Alquichire, Said J.; Gómez-Tejedor, José-Antonio; Vallés Lluch, Ana; Diaz, Luis E.; Valero, Manuel F. (Cambridge University Press (Materials Research Society), 2017)

[EN] Polyurethane-based bioadhesive was synthesized with polyols derived from castor oil (chemically modified and unmodified) and hexamethylene diisocyanate with chitosan addition as a bioactive filler. The objective was ...
Polyurethanes from modified castor oil and chitosan. Synthesis, characterization, in vitro degradation, and cytotoxicity

Arévalo-Alquichire, Said; Ramírez, Claudia; Andrade, Laura; Uscategui, Yomaira; Diaz, Luis E.; Gómez-Tejedor, José Antonio; Vallés Lluch, Ana; Valero, Manuel F. (SAGE Publications, 2018)

[EN] Polyurethanes (PUs) from castor oil (CO), modified CO (MCO) by transesterification reaction, isophorone diisocyanate (IPDI) in an NCO/OH ratio equal to 1, and chitosan (CS) were synthesized to assess their potential ...
