  Strongly amphiphilic wetting behavior for polyurethanes with polyoxetane soft blocks having –CF2H terminated side chains

  摘要：

  Two novel polyoxetanes with -CF2CF2H (4F) or -(CF2)(3)CF2H (8F) terminated side chains were synthesized and characterized by H-1 NMR spectroscopy, DSC and GPC. 4F and 8F diols were incorporated in polyurethanes IPDI-BD(40)/4F-8.2 (U-4F-8.2) and IPDI-BD(40)/8F-5.8 (U-8F-5.8), where isophorone diisocyanate (IPDI) and 1,4-butane diol (BD) comprise the hard block (40 wt%) and 4F-8.2 or 8F-5.8 are soft blocks with M-n in kDa. Surface characteristics were evaluated using TM-AFM, XPS and dynamic contact angle (DCA) measurements. In contrast to U-4F-8.2, TM-AFM reveals an interesting phase separated surface morphology for U-8F-5.8 apparently driven by higher F side chain content. A model is proposed to account for contact angle measurements that show reversible, strongly amphiphilic wetting with theta(adv) > 100 degrees and theta(rec) < 40 degrees. Resistance to surface phase separation and related studies suggest the -CF2CF2H moiety is an important candidate for expanding the range of functional groups employed in surface modifiers.
