Bottle-Brush copolymers, where two or more different types of side chains are attached to a linear polymer, may open up an alternative approach to fabricate domain spacing with large length scale. In that case, each side chain may be designed long enough to drive microphase separation and thus behave like a block segment in a conventional block copolymer. Moreover, brush polymers has been considered to have the highly extended backbone conformation and exhibit the reduced degree of entanglements between brush polymers compared with conventional, due to the significant steric hindrances between densely grafted side brush chains. Here we consider microphase separation of various type of bottle-brush copolymers in their molten states using strong segregation theory and Monte Carlo simulations, discusssing their molecular packing in the formed periodic structure as well as the behaviors of order-disorder transition and molecular weight dependence of the interdomain size, etc |
