Synthesis and Applications of Fluoroalkyl End-capped Oligomeric Nanoparticles

1 Results Considerable interest has been devoted in recent years to block copolymers containing fluoroalkyl groups owing to exhibiting the low surface energy and the self-assembled polymeric aggregates resembling micelle in aqueous and organic media, which cannot be achieved in the corresponding randomly fluorinated copolymers1].In these fluorinated block copolymers, we have found that ABA triblock-type fluoroalkylated oligomers and dendritic-type fluoroalkyl end-capped block copolymers can be prepared by the use of fluoroalkanoyl peroxide as a key intermediate2].Interestingly, these fluorinated block polymers can form the nanometer size-controlled self-assembled molecular aggregates with the aggregation of end-capped fluoroalkyl segments in aqueous and organic media3].More interestingly, these fluorinated molecular aggregates thus obtained could interact with a variety of guest molecules such as organic dyes, low-molecular biocides, metal nanoparticles, calcium carbonates, fullerenes, single-walled carbon nanotubes, nanodiammonds and magnetites to afford stable fluorinated molecular aggregates-guest molecules nanocomposites3].
