The microphase separation behavior of Janus bottlebrush copolymers and Janus bottlebrush copolymers with solvent swelling were evaluated theoretically with dissipative particle dynamics (DPD) modeling. The programs systematically tested conditions to determine trends in behavior. Changes in the weight fractions of the A and B polymer components found that lamellae or bicontinuous phases were dominant for most conditions. Other parameters studied within the bottlebrush copolymer system included backbone size, brush length, and thermodynamic favorability of A-B interactions in the system. Solvent swelling of the B monomer type was observed to increase the curvature of the A polymer domains. For each condition, the structure factor aided in phase identification. The underlying causes of behavior are inferred and discussed. Phase diagrams were created for the bottlebrush copolymer systems for future prediction of the separation behavior. Results of this study touch upon the fields of energy storage, high precision patterning, and electronics.
