Mobility of Free Ends and Junction Points as a Lamellar Block Copolymer

Abstract: The dynamics of diblock copolymers organized into a lamellar microstructure has been simulated on a cubic lattice. The chains of AioBio are present at a volume fraction of 0.847 and the reduced pairwise interaction energy between A and B is 0.5, which places the system near the microphase separation transition. Parallel simulations were performed in which the voids participated in no interactions with either block and in which they behaved as monomeric species of B. The motion is monitored for the beads at the… Show more

“…Mattice and coworkers have developed a mapping from a rotational isomeric state (RIS) description of a polymer onto a diamond lattice for the second nearest neighbour positions of polyolefine backbones [66][67][68][69]. The intermolecular potential in this model, with different values of the energy for different ranges of distances between the superatoms, was tuned by aiming at producing a zero second virial coefficient (corresponding to theta-conditions) as well as a correct radius of gyration for polymers such as polyethylene and polypropylene.…”
