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.
