Micellar morphology of a semifluorinated diblock copolymer

Surface properties and structures of diblock copolymer and homopolymer with perfluoroalkyl side chains

“…In this study, HCFC-225 dissolved both segments, while the PFEMA segments were insoluble in chloroform. Thus, when dissolving PMMA-b-PFEMA in chloroform, it will form micelles composed of the MMA corona and the PFEMA core [23][24][25]. Fig.…”

“…For example, there are only a few solvents such as fluorinated solvents and supercritical carbon dioxide for dissolving them [16]. To overcome these problems, polymers with perfluoroalkyl side chains and their copolymers have been extensively investigated [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. We also synthesized random and diblock copolymers, composed of methyl methacrylate and 2-perfluorooctylethyl methacrylate (PMMA-r-PFEMA, PMMA-b-PFEMA, respectively), with the PFEMA content around 15 mol% [31].…”

Switching surface polarity: synthesis and characterization of a fluorinated block copolymer with surface‐active tert ‐butoxycarbonyl groups

“…In addition to these studies, such materials have been used recently as surfactants in supercritical CO 2 6 owing to their unusual character as a micelleforming amphiphile in non-polar solvents. 7 Many approaches exist for the incorporation of fluorinated blocks, but they generally involve either the living polymerization of fluorinated monomers, largely acrylates, 7,8 or the modification of block copolymers prepared by anionic polymerization. 2,9,10 Recently, a new family of polymers was described using a mild direct fluorination reaction, 9 but most other examples involve the attachment of readily available fluorinated acids 2,11 as described in this paper.…”

Composition and solution properties of fluorinated block copolymers and their surface structures in the solid state

“…The micelles and unimers coexisted in solution when the fluorine content in the copolymer was very low. As the length of PFMA block increased, the micelles readily formed and became more stable with increasing diameters [21][22][23] , while the unimers disappeared at higher PFMA block lengths.…”
