Metal coordinating comonomers influence the transition metal complex, polymer–metal ion binding, and subsequently material properties in magnetic responsive poly(ionic liquid)s.

Tertiary amine-modified corn starches were converted to their basic or hydroxide form and combined with carboxylated butadiene-acrylonitrile copolymer and butadiene-styrene-sulfonic acid polymer to produce ionically bonded filler-elastomer composites. An increasing percentage of the elastomer fraction in the starch-elastomer composite is insolubilized as the starch-to-elastomer ratio increases....

This review article deals with the ionic conductivity of solid-state electrolytes for lithium batteries. It has discussed mechanisms ion conduction in ceramics, polymers, and ceramic-polymer composite electrolytes. In ceramic electrolytes, transport is accomplished mobile point defects a crystal. Li+ ions migrate mainly via vacancy mechanism, interstitial or interstitial-substitutional exchange...

nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. solvent casting method was used to prepare cobalt oxide (co3o4) dispersed poly (methyl methacrylate) (pmma) nano composite. x-ray diffraction tool is used to know the structural...

Several generations of ionic polymer metal composite (IPMC) actuators have been developed since 1992. It has been discovered that the composite electrodes which are composed of electronic and ionic conductors, have great impact on performance of ionic polymer actuators by affecting strain level, efficiency and speed. One of important factors in composite electrodes is the shape and morphology o...

In this study, a calcium-containing monomer, namely calcium lactate, was used for the synthesis of calcium-containing polyurethane for use in biomedical applications. Ether-based polyurethane was prepared using poly(oxytetramethylene)glycol, hexamethylene diisocyanate and calcium lactate. The prepared polymer was characterized by FTIR spectroscopy, which confirmed the presence of ionic linkages...

The main theoretical concepts on ionic conduction at interfaces, especially the space charge layer model, are summarized in the ®rst part of this review: ion trapping or redistribution leads to charge carrier accumulation, depletion or inversion and, consequently, to conductivity changes in composite materials. Experimental con®rmations of the space charge layer model and the complementary perc...

This Communication describes a method of fabricating complex metallic microstructures in 3D by injecting liquid solder into microfluidic channels, and allowing the solder to cool and solidify; after fabrication, the metallic structures can be flexed, bent, or twisted. This method of fabrication—which we call microsolidics—takes advantage of the techniques that were developed for fabricating mic...

Thermally responsive polymer-metal nanoparticle composites couple the ability of certain metal nanoparticles to convert external stimuli to heat with polymers that display sharp property changes in response to temperature changes, allowing for external control over polymer properties. These systems have been investigated for a variety of biomedical applications, including drug delivery, microfl...
