The self-assembly behavior of core-shell bottle brush (CSBB) copolymers are investigated by using Monte Carlo (MC) simulations. Here the CSBB is defined as a bottle brush polymer where AB diblock side chains each with a grafting A block and a terminal B block are grafted to A-type backbone. Simulating the morphological structures of molten CSBB, the order-disorder transitions (ODTs) were investigated as a function of the degree of incompatibility (χN) and the backbone length (M), which were compared to Random Phase Approximation (RPA) theory. To interpret the architecture effect, the investigation of ODT behavior were extended to a general bottle brush architecture expressing in terms of grafting position along the side chain. The ODT curves in the χN-M space show the promotion of ordered phase as the backbone length increases, which suggest the enhancement of ordering of short building block via controlling chain architecture. |
