## Abstract Surface chemical analysis of two commercially available polyurethanes, i.e., Avcothane and Biomer was carried out by electron spectroscopy for chemical analysis (ESCA). The depth which is subject to analysis is in the range of 50–100 Å. The variables studied in this study are the differ

## Abstract Segmented polyurethane (PU) films from castor‐oil‐based PU prepolymer with different hard‐segment compositions and nitrolignin (NL) were synthesized. Diisocyanates (DIs), such as 2,4‐tolylene DI (TDI) and 4,4′‐diphenylmethane DI (MDI), 1,4‐butanediol (BDO) as a chain extender, and trime
The functional and biochemical heterogeneity of platelets has been studied using graded differential centrifugation to fractionate human platelets according to size while maintaining their morphological and functional integrity as indicated by scanning electron microscopy and content of P-thromboglo
Polyurethanes are widely used as biomaterials for medical implants because of their excellent mechanical properties and moderate biocompatibility. However, the demand for more bioresistant and biocompatible polyurethanes to meet the needs of long-term implant devices still remains an important issue
A series of polyurethane compositions with soft and hard segments were prepared, and the damping and mechanical properties of these materials were studied. The damping of polyurethane was decreased and shifted to the higher temperature with the content of butanediol (BD) used as a chain extender. Th
