 note = {[Abstract] Polyurethnaneureas (F-PEUU) including the fluorinated alkane moiety in the main chain were obtained from a typical two step polyaddition of polytetrahydrofuran (PTHF) to 4,4'-diphenyl methane diisocyanate (MDI) in the presence of perfluoroalkanediol (PFADO), such as 2,2,3,3,4,4,5,5-octafluoro1,6-hexanediol (OFHDO) or 2,2,3,3,4,4,5,5,6,6,7,7- dodecafluoro-1,8-octanediol (DFODO), using ethylenediamine (EDA) as a chain extension reagent.Polyaddition with a molar ratio of 1:2:1 for PTFH + PFADO:MDI:EDA gave the F-PEUU in dimethyl sulfoxide , where the molar ratio of the PFADO moiety was changed from 0.1 to 0.3. From the contact angle measurement, it was found that the contact angle of water is increased from 71° to 91° with increasing the molar ratio of the PFADO moiety. This means that the introduction of the PFADO moiety into PEUU results in higher hydrophobicity of film surface. Scanning probe microscope (SPM) observation showed the micro-phase separation (sea-island) structure on the surface of the F-PEUU. From tension strength test, the elastic modulus and ultimate elongation of F-PEUU film were found to be 29.3MPa and 401％, respectively. In cell culture test, the F-PEUU films showed non-adhesiveness of HeLa cell. Because of their mechanical and biocompatible properties, F-PEUUs are expected to be useful materials as an artificial heart and blood vessel., application/pdf},
