  FLUORINATED ZWITTERIONIC POLYMERS AND METHODS OF USE

  摘要：

  Fluorinated monomer compositions having the formula: A-L-Z (1), wherein A is a polymerizable group (e.g., a vinyl group); L is a bond or linking portion; Z is a zwitterionic moiety or a zwitterionic precursor moiety containing a protecting group capable of deprotection to form a charged group; wherein at least one hydrogen atom in A, L, and/or Z in Formula (1) is substituted by a fluorinated hydrocarbon group, wherein the fluorinated hydrocarbon group contains 1-12 carbon atoms and precisely or at least one, two, three, four, five, or six fluorine atoms. Also described herein are fluorinated zwitterionic polymers derived from such monomers. Also described herein are mixed-charge zwitterionic polymers. Other aspects include methods for producing the monomers and polymers, bulk material (e.g., hydrogel or copolymer hybrid) compositions of any of the zwitterionic polymers described herein, fouling-resistant and/or fouling releasing surfaces and objects, and nanoparticles containing the polymer or bulk material.
