LIVING SELF-ASSEMBLY OF FIBER-LIKE MICELLES BY POLYFERROCENYLSILANE BLOCK COPOLYMERS

摘要：

Polyferrocenyldimethylsilane (PFS) block copolymers form cylindrical micelles in selective solvents for a wide range of compositions in which the soluble block is longer than the insoluble and semicrystalline PFS block. The most striking feature of the micelle formation mechanism is that the micelles grow by a seeded living epitaxial growth mechanism in which new polymer added to a solution of the micelles adds exclusively to the ends of exiting micelles.1 While an analogous mechanism has been identified for the growth of protein fibers such as actin, tubulin and P-amyloid fibers, PFS block copolymers are the only synthetic polymers that form micelles in this way.
