Abstract

Synthetic biodegradable polymers are considered strategic in the biomaterials field and are used in various applications. Among the polymers used as biomaterials, polyurethanes (PUs) feature prominently due to their versatility and the ability to obtain products with a wide range of physical and mechanical properties. In this work, new biodegradable polyurethane films were developed based on hexamethylene diisocyanate (HDI) and glycerol as the hard segment (HS), and poly(caprolactone) triol (PCL triol) and low-molecular-weight poly(ethylene glycol) PEG as the soft segment (SS) without the use of a catalyst. The films obtained were characterized by structural, mechanical and biological testing. A highly connected network with a homogeneous PU structure was obtained due to crosslinked bonds. The films showed amorphous structures, high water uptake, hydrogel behavior, and susceptibility to hydrolytic degradation. Mechanical tests indicated that the films reached a high deformation at break of up to 425.4%, an elastic modulus of 1.6 MPa and a tensile strength of 3.6 MPa. The materials presented a moderate toxic effect on MTT assay and can be considered potential materials for biomedical applications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
