Biomaterials based on new polyurethane and hydrolyzed collagen, k-elastin, hyaluronic acid and chondroitin sulfate.


Journal Article

In this paper biomaterials based on various polyurethane formulations have been physically characterized by FT-IR spectroscopy, contact angle measurements, DSC, TG/DTG and SEM methods. It has been established that the transition temperatures of soft and hard segments of polyurethane (glass transition or melting) depend on the blend composition. The melting temperature varies from 54.2 to 81.9°C for soft segments, and from 220 to 235°C for hard segments. FT-IR spectrometry allows identifying the functional groups involved in interactions and consequently the changes in polymer chain mobility. From SEM images, is evident that polyurethanic film is porous and spongious. By adding of the others components such as hydrolyzed collagen, elastin, chondroitin sulfate or hyaluronic acid, a reduction of porosity of films was obtained.
