Gel polymer electrolytes (GPEs) made of blends of ionic liquids and polymer elements, are of high interest as electrolytes in batteries.
The usage of blends of ionic liquids and organic solvents has been considered as a feasible strategy since these electrolytes combine high usable voltages and good transport properties at the same time.
The nanocomposite film prepared by solution-blending of ionic liquid modified CNF i-CNFF) and ultrahigh molecular weight polyethylene (UHMWPE) displayed better toughness when compared with pure UHMWPE even at very low concentrations (e.g. 0.4 wt%).
Novel blends made of ionic naphthalene thermotropic polymer (NTP) and poly ethylene terephthalate) (PET) have been prepared by melt mixing.
Heterophase water-in-oil polymerizations of acrylamide have been conducted in the presence of blends of non-ionic stabilizers at moderate monomer concentrations (20%).
It is sodium lauryl sulphate free and consists of a proprietary blend of non-ionic and amphoteric surfactants that, when combined, result in large, gentle cleansing micelles.
This approach is analogous to the use of ionic blend compatibilizers in creating well-dispersed polymeric blends, with the difference being that one of the components in the blend is an inorganic nanoparticle (which has been shown to lead to an additional entropic penalty that has to be overcome).
Homogeneous blends were formed when a small amount (5 wt%) of ionic NTP was blended with PET; but, phase separation occurred at a higher composition of the ionic NTP (10 wt%).
The obtained blend membranes were characterized in terms of ionic conductivity by impedance spectroscopy, in terms of morphology by transmission electron microscopy (TEM), and in terms of thermal stability by TGA.
Such changes in deformation mode can be understood as arising from an increase in the 'effective' strand density due to the formation of ionic cross-links upon blending.
Dynamic mechanical properties of three different styrene-based ionomer blends containing ca. 5 mol% of ionic repeat units were investigated; the three ionic units were itaconate (ITANa), methacrylate (MANa), and styrenesulfonate (SNa).
