A dissipative particle dynamics simulation was performed to study the
influence of blending different linear triblock copolymers
AxByCz and linear diblock copolymers AmBn in an aqueous
solution on the morphology diversity of the formed multicompartment micelles.
The chain lengths of the linear triblock copolymers and diblock copolymers were
varied to find the conditions of the formation of multicompartment micelles. The
multicompartment micelle morphologies formed by the different blends of linear
triblock copolymer and linear diblock copolymer are various, such as "worm-like"
micelles, "hamburger" micelles, "sphere on sphere" micelles, and
"core-shell-corona" micelles etc. Controlling the overall morphology and inner
structure of the multicompartment micelles was possible using binary blends of a
linear triblock copolymer and a diblock copolymer. The density profiles and the
pair distribution function were calculated to characterize the structures of the
obtained multicompartment micelles. In this work, by blending a linear triblock
copolymer and a linear diblock copolymer, complex multicompartment micelles were
prepared and characterized. This work shows that simply blending linear triblock
copolymers and linear diblock copolymers is an effective way to control the
morphology and structure of multicompartment micelles. This is more economical
and easy to form multicompartment micelles in the engineering experiments.
Therefore, the blending of copolymers should be given more attention in future
for the design of new multicompartment micelles.
