SELF-ASSEMBLY OF LINEAR ROD-COIL MULTIBLOCK COPOLYMERS
The self-assembly of the linear rod-coil multiblock copolymers is studied by applying self-consistent-field lattice techniques in a three-dimensional (3D) space. Compared to the copolymer with one rod
the copolymer with more rods (
m
rod
≥ 2) exhibits rich order-order phase transitions with increasing temperature
where the ordered morphology changes from strips to perforated lamellae and finally to lamellae. In addition
taking the copolymer with
m
rod
= 2 as a representative
we further study the effects of the volume fractions of the rods
the spacer coils and the end coils on the phase behaviors respectively
by which the detailed self-assembled mechanism of the linear rod-coil multiblock copolymers is revealed. Our results are expected to provide guidance for the design of the rod-coil materials.
