Recently, a method of inducing nanometer-scale pores by selectively swelling hydrophilic blocks in an amphiphilic block copolymer thin film has attracted attention as a non-destructive pore induction method. Herein, fluorinated block copolymers with very high solubility differences between blocks are synthesized by ring-opening metathesis polymerization(ROMP). Monomer structure was fine-tuned to allow for an efficient initiation of the fluorous block from the terminus of an organic soluble block. Additionally, self-assembly behavior and its relationship to the fluorine content of the fluorous block was studied. Thin films of the fluorous block copolymers could be treated with fluorous solvents to produce highly hydrophobic nanoporous membranes. Such a block copolymer can be applied to various fields such as a low dielectric material, a low refractive material, a coating material, and a drug delivery thin film by utilizing the inherently low surface energy of a fluorinated polymer. |
