| Outline of Final Research Achievements |
Fluoroalkyl end-capped oligomer/guest molecule composites were prepared by the sol-gel reactions of the corresponding oligomer in the presence of a variety of guest molecules such as micrometer size-controlled silica particles and cyclodextrin polymer fine particles. Especially, it was clarified that the composites thus obtained can exhibit a unique surface wettability such as superoleophobic/superhydrophobic (superamphiphobic), superoleophilic/superhydrophobic and superleophobic/superhydrophilic characteristics. In addition, these fluorinated composites were applied to not only the packing materials for the separation of water/oil but also the separation membrane of water/oil. More interestingly, the fluorinated oligomer/magnetite composite powders were applied to the demulsification of W/O emulsion to isolate the transparent colorless oil under a magnetic field.
