Synthesis and Surface Properties of Superhydrophobic Polyurethane |
| 초록 |
Novel fluorinated polyurethane elastomers were synthesized by two step urethane reaction of the fluorinated polyols based on poly(vinylidenefluoride-co-hexafluoro perpene)(2,000g/mol) or Fomblin ZDOL®(2,000g/mol) and diisocyanate such as 4,4'-methylene-bis(phenyl isocyanate)(MDI) in the presence of a solvent (DMAc/THF;3/1), followed by subsequent chain extension with 1,4-butanediol. In order to control the fluorinated polyol moiety of the soft segment in the synthesized elastomer to 10~50mol%, polyether type polyols such as polytetramethylene glycol(PTMG; 2,000g/mol)) were mixed during the polymerization reaction. The structure and surface properties of polyurethane containing fluoropolyols were confirmed by using FT-IR, XPS and Water Contact Angle meter. |
