Effect of salt concentration on the conductivity of PEO-based composite polymeric electrolytes
Article Abstract:
The influence of salt concentration on the molal conductivity of poly(ethylene oxide) (PEO)-based composite polymeric electrolytes has been studied. These compounds are the most-studied polymer ionic conductors due to the influence of PEO in fast ion transport. PEO shows good complexation, high flexibility and excellent mechanical properties even up to its melting point. Results show the addition of various organic or inorganic fillers alters the conductivity of the polymeric electrolytes. The changes are due to the interactions of the Lewis acid base with the filler, Li+ cations and the base centers of polyether oxygens.

Structure of nanometric silica clusters in polymeric composite materials
Article Abstract:
A study was conducted, using small angle neutron scattering (SANS) and transmission electron microscopy (TEM), to characterize the local and mean particle distribution in the dry film. The result shows that the nanosize silica particles can self-assemble into a well-ordered arrangement, while the suspension concentrates and a dry composite film is formed with clusters of particles.

Core-shell structure of degradable, thermosensitive polymeric micelles studied by small-angle neutron scattering
Article Abstract:
Small-angle neutron scattering (SANS) is used for studying the structure of assemblies of block copolymers composed of thermosensitive, biodegradable poly(N-(2-hydroxypropyl) methacrylamide-dilactate) and poly(ethylene glycol). The experiment has provided accurate information on how the hydrophobicity of the core and its stability are changed with the incubation time.
