Sprayable Elastic Conductors Based on Block Copolymer Silver Nanoparticle Composites
Block copolymer silver nanoparticle composite elastic conductors were fabricated through solution blow spinning and subsequent nanoparticle nucleation. The reported technique allows for conformal deposition onto nonplanar substrates. We additionally demonstrated the ability to tune the strain dependence of the electrical properties by adjusting nanoparticle precursor concentration or localized ...
متن کاملBlock copolymer/ferroelectric nanoparticle nanocomposites.
Nanocomposites composed of diblock copolymer/ferroelectric nanoparticles were formed by selectively constraining ferroelectric nanoparticles (NPs) within diblock copolymer nanodomains via judicious surface modification of ferroelectric NPs. Ferroelectric barium titanate (BaTiO3) NPs with different sizes that are permanently capped with polystyrene chains (i.e., PS-functionalized BaTiO3NPs) were...
متن کاملCoarse-grained molecular dynamics study of block copolymer/nanoparticle composites under elongational flow.
Symmetric diblock copolymer/nanoparticle (NP) systems under planar elongational flow have been modeled and simulated using coarse-grained nonequilibrium molecular dynamics. The aim of our present study is to understand how the dispersion of NPs in a block copolymer system is influenced by elongational flow and how the presence of NPs changes the rheology and flow-induced morphology transition i...
متن کاملModeling Microscopic Morphology and Mechanical Properties of Block Copolymer/Nanoparticle Composites
The morphology of block copolymer and nanoparticle composites depends not only on the copolymer architecture but also on the surface energy, geometry, and volume fraction of the embedding nanoparticles. Toward a quantitative description of the composite structure and associated thermomechanical properties from a molecular perspective, we examined the performance of a nonlocal density functional...
متن کاملNanoparticle-Induced Phase Transitions in Diblock-Copolymer Films
Incorporation of nanoparticles into self-assembled block copolymers has been explored as an efficient way for improving the mechanical strength, electrical conductivity, and optical properties of materials at the nanometer scale. Recent computer simulations predict that the cooperative self-organization of nanoparticles and block copolymers should yield a wide variety of structures with well-co...
