Summary: In this study, PP/nanoclay nanocomposites were prepared by biaxial stretching method, which showed improved oxygen barrier properties with increased draw ratio and nanoclay content, resulting in a reduced oxygen permeability value of 43.5 cc center dot mm/m(2)center dot day center dot atm. The composite also exhibited stable oxygen permeability values under increased relative humidity, along with enhanced mechanical and thermal properties. The biaxially-stretched PP/nanoclay nanocomposite shows potential as a replacement for multi-layered packaging materials.

Summary: High-frequency actuators based on non-flammable lithium-ion conducting phosphate liquid crystal-polymer composite electrolytes have been developed. These actuators bend at frequencies up to 80 Hz under an AC voltage of 2 V, thanks to their high ionic conductivity of 10(-4) S cm(-1) at room temperature. The composite electrolytes consist of a 2D ion-transport pathway formed by an equimolar complex of a phosphate-containing mesogenic molecule and lithium bis(trifluoromethylsulfonyl)imide.

Summary: We propose a novel liquid-state polymer electrolyte composed of LiFSI salts, DME solvents, and polysiloxane tethered with ion-solvating moieties. Anchored solvent molecules can increase the ionic conductivity of the electrolyte without undermining its non-flammability. The resulting non-flammable polymer electrolyte has a room-temperature ionic conductivity of 1.6 mS/cm and a wide operation window of 25?-100?, and can pair with commercially available electrodes without further cell engineering.

Summary: A PPC nanocomposite with highly exfoliated nanoclay was prepared through a solution intercalation process. The highly exfoliated nanoclay contributed to a viscosity reduction and a slight reduction in molecular weight of PPC, with the minimum or critical concentration of nanoclay found to be between about 0.5% and 2.0%. The PPC nanocomposites with lower viscosity showed excellent precursors for making PU coating materials, which exhibited higher anticorrosive properties compared to non-modified PU coatings.

Summary: The aim of this research was to develop a self-healing dental nanocomposite and evaluate its mechanical properties, crack-healing, and self-healing longevity after water aging. Nanocapsules were synthesized as they are biocompatible for dental materials, and nanoclay was used as a filler to improve mechanical properties. The results showed that incorporating nanocapsules into the nanocomposite increased mechanical properties and achieved good self-healing efficiency, which was not affected by water aging.
