Structure of microemulsion-ABA triblock copolymer networks.
Structural equilibrium properties of transient networks formed by microemulsion droplets and ABA triblock copolymers in solution have been studied by Monte Carlo simulation. The droplets were represented by soft spheres, and the polymers were represented by junctions connected by harmonic bonds with an angular potential regulating the intrinsic chain stiffness. The interaction parameters were s...
متن کاملWell Ordered Polymer Melts from Blends of Disordered Triblock Copolymer Surfactants and Functional Homopolymers
Microphase segregated block copolymer melts and solids have long garnered significant scientific interest due to their ability to spontaneously form periodic morphologies at controllable length scales. Their utility as stand-alone nanostructured functional materials or as templates for the fabrication of hierarchical solids is well documented. However, their deployment in large scale applicatio...
متن کاملComparison of A-block polydispersity effects on BAB triblock and AB diblock copolymer melts.
Recent experiments on triblock copolymer melts suggest that polydispersity effects are dramatically enhanced when polydisperse blocks are constrained by both ends to the internal interfaces of an ordered morphology. To quantify the relevance of architecture, we compare BAB triblock and AB diblock copolymer melts with polydisperse A blocks and monodisperse B blocks, using self-consistent field t...
متن کاملLateral structures of buried interfaces in ABA-type triblock copolymer films.
The lateral structure of an ABA-type triblock copolymer polyparamethylstyrene- block-polystyrene- block-polyparamethylstyrene at the buried silicon substrate interface is studied as a function of different substrate surface treatments. With grazing incidence small-angle neutron scattering (GISANS), high interface sensitivity is reached. With GISANS, the orientation and degree of order of the mo...
