Chemical structure of diisocyanates, poliols and chain extenders affect biocompatibitity of obtained polyurethanes. Hard segments of polyurethanes for biomedical applications are based on both aromatic and aliphatic diisocyanates. The obtained materials have different physico-mechanical properties and their interactions with live tissue.
In this study, polyurethanes with different hard segment diisocyanates (MDI, HMDI) were obtained and their structure, physical properties and biocompatibility were studied. Scanning electron microscopy (SEM), differental scanning calorimetry (DSC), contact angle measurments were used for polyurethane properties characterization.
