“…Similarly, in solvent-swollen systems, the presence of solvent results in a reduction of mechanical properties. Previous studies have utilized a range of strategies for augmenting structural properties in polymer electrolytes, including cross-linking, , ceramic particle fillers, , hybrid organic−inorganic polymers, , clay fillers, fiber fillers, and block copolymers. − However, these approaches have been unable to demonstrate superior mechanical properties while maintaining useful ion conductivity.…”

Polymer electrolytes were investigated for potential use in multifunctional structural batteries requiring both mechanical and electrochemical properties. Electrolytes were formulated with a broad range of multifunctional behaviors, spanning continuously from highly conductive and structurally weak materials to poorly conductive and highly structural materials. Solvent-free polymer scaffolds were synthesized from monomers containing poly(ethylene glycol) (PEG) oligomers and one to four vinyl ester groups. The electrolytes were formed by dissolving lithium trifluoromethanesulfonate in the monomers prior to thermal cure. Electrochemical, mechanical, and viscoelastic properties were studied with respect to salt concentration, polymer chemistry, and polymer architecture. The addition of salt was found to have minimal impact on compressive stiffness, whereas it increased T g and significantly influenced ion conductivity, with a maximum conductivity at 9−12% salt w/w PEG. At a constant salt concentration, the homopolymer electrolytes exhibited close to a 1:1 inverse correlation between conductivity and stiffness as monomer composition was changed.

“…According to literature reports, self-assembled PEO monolayers were used as a template to direct the nucleation and the subsequent oriented growth of TS-1 thin films . Hybrid polymer−inorganic nanocomposite materials that contain both PEO and zeolite components revealed new chemical and physical properties . PVA−zeolite composite materials were used as catalysts in hydrogenation and as organic−inorganic composite membranes in ethanol dehydration .…”

The b-oriented monolayers of microsized silicalite-1 crystals have been manually assembled on glass plate supported poly(ethylene oxide) (PEO), poly(vinyl alcohol) (PVA), chitosan, and poly(methyl methacrylate) (PMMA) thin films via hydrogen bonding with much enhanced binding strength and satisfactory degrees of coverage and close packing. The exerted pressure and rubbing time in the manual assembly do not affect the binding strength of the silicalite-1 monolayer on the glass plate supported polymeric film. This manual assembly has been further applied to fabricate zeolite monolayers on commercially available Plexiglas surfaces and b-oriented multilayered films of silicalite-1 crystals on glass plates. The assembly method established in this study provides a feasible way to produce zeolite monolayers on polymer-modified solid substrates and Plexiglas and to fabricate zeolite-polymer composite membranes by means of the layer-by-layer technique.
