Graphene-Based Polymer Nanocomposites
Materials science continues to occupy a central place in our lives primarily through the design and creation of new materials, and our quality of life has improved over time thanks to the discovery of new materials. Major milestones in the advancement of our society are intimately associated with materials throughout history: the stone age, bronze age, iron age, steel age (industrial revolution...
متن کاملDynamics in Polymer Nanocomposites
Polymer diffusion and matrix morphology are investigated in polymer nanocomposites (PNCs). Using elastic recoil detection, tracer diffusion coefficients (D) of dPS and dPMMA are measured in PNCs containing polystyrene (PS) with phenyl-capped (Ph) silica, and poly(methyl methacrylate) (PMMA) with hydroxylterminated (OH) silica nanoparticles (NPs), respectively. As NP volume fraction increases or...
متن کاملGold Nanorod Linking to Control Plasmonic Properties in Solution and Polymer Nanocomposites
A novel, solution-based method is presented to prepare bifunctional gold nanorods (B-NRs), assemble B-NRs end-to-end in various solvents, and disperse linked B-NRs in a polymer matrix. The B-NRs have poly(ethylene glycol) grafted along its long axis and cysteine adsorbed to its ends. By controlling cysteine coverage, bifunctional ligands or polymer can be end-grafted to the AuNRs. Here, two dit...
متن کاملEffective Optical Properties of Plasmonic Nanocomposites
Plasmonic nanocomposites find many applications, such as nanometric coatings in emerging fields, such as optotronics, photovoltaics or integrated optics. To make use of their ability to affect light propagation in an unprecedented manner, plasmonic nanocomposites should consist of densely packed metallic nanoparticles. This causes a major challenge for their theoretical description, since the r...
متن کاملSonochemical preparation of polymer nanocomposites.
This review covers sonochemical fabrication of polymer nanocomposites. In addition to its application to the synthesis of various polymeric systems, due to its powerful efficiency, sonochemistry has been widely used not only as the assistant of dispersion for nanomaterials such as carbon nanotubes (CNT) and organophillic clay, but also as a special initiator to enhance polymerization for fabric...
