Micellar structures of linear triblock terpolymers: Three blocks but many possibilities

Abstract

The combination of the inherently complex structure of ABC triblock terpolymers with careful selection of the assembly conditions can yield an incredible array of nanostructures in solution. In this review we will highlight recent progress in the self-assembly of triblock terpolymers in solution. We will discuss various approaches that are available to tune triblock terpolymer assembly. These approaches include changing the block sequence, the block ratios, adjusting the solvent conditions, incorporating stimuli-responsive or crystalline blocks, and employing complexation agents. Triblock terpolymer self-assembly in solution has so far produced core–shell–corona systems, multicompartmental micelles, Janus systems, helices, micelles with segregated coronas, and numerous other systems.
