    Nanosilica particles are excellent morphological stabilizers, effective in preventing coalescence regardless of the processing or post-processing technique involved. The silica nanoparticles create a rigid barrier along PP-PA interface that promotes a reduction in the droplet size and polydispersity. The increment in the non-linearity parameter Q measured under LAOS conditions evidences the interactions between nanosilica particles and the blend components.

    A convection-diffusion porous model is derived to characterize moisture transport in polymeric composites at high temperatures. The coupling of convection and diffusion is achieved by combining the law of conservation of mass, Darcy's law, the relation for liquid-vapor chemical equilibrium, and the ideal gas law. The proposed convection-diffusion model is more effective in interpreting moisture desorption that occurs in a very short time at high temperature. Vapor pressure evolution can also be predicted.

  3. Short-time elasticity of polymer melts: Tobolsky conjecture and heterogeneous local stiffness

    On the picosecond time scale, the shear response of uncrosslinked polymer melts G(t) is local, heterogeneous, and mainly due to the bonds. As a consequence, the neighborhood of the end monomers is softer than the one of the inner monomers and the modulus is chain-length dependent. For intermediate times, G(t) approaches the relaxed plateau Gp, which does not depend on the chain length and is largely set by the non-bonding interactions.

  4. Poly((2-alkylbenzo[1,2,3]triazole-4,7-diyl)vinylene)s for organic solar cells

    Poly{(2-alkylbenzo[1,2,3]triazole-4,7-diyl)vinylene}s (pBTzV polymers) synthesized with long straight-chain and branched-chain alkyl pendants show significant substituent effects on absorption spectra, morphology, ambipolar charge mobility, and on solar cell power conversion when used as active layer constituents with PC71BM. Overall, the results indicate that pBTzV and analogous electron-deficient poly(arylene vinylene)s are appropriate targets to develop for electronic material uses.

  5. Challenges and rewards of the electrosynthesis of macroscopic aligned carbon nanotube array/conducting polymer hybrid assemblies

    Balazs Endrődi, Gergely Ferenc Samu, Dora Fejes, Zoltan Németh, Endre Horváth, Andrea Pisoni, Peter Krisztian Matus, Klara Hernádi, Csaba Visy, Laszlo Forró and Csaba Janáky

    Electrosynthesis of macroscopic hybrid materials, based on well-aligned carbon nanotube arrays and different conducting polymers, is demonstrated. Composition and morphology dependent properties are exploited in thermal management, thermoelectric power generation, and electrochemical charge storage. By comparing and contrasting the results obtained for the various composites, structure-property relationships are established and discussed.
