“…Based on these results, the ions constituting the IL dissociate in the starch matrix and an ion hopping mechanism within the polymer matrix is inferred. 59,60 The conductivity of TPS_EMIm-SO 4 Et, TPS_EMIm-N-(CN) 2 , and TPS_EMIm-Cl films conditioned at RH of 40% decreased and the activation energy increased with respect to the results acquired at RH = 50% (Table S2). On the other hand, an interesting result was found for films plasticized with EMIm-OAc, for which it was observed that the conductivity and the activation energy at 50 and 40% RH remained almost unchanged.…”

Recently, imidazole-based ionic liquids have been widely used as starch plasticizers. These salts are very effective in transforming starch, a widely available and inexpensive biopolymer, into biodegradable films with good mechanical properties and ionic conductivity. These films could have interesting applications in flexible electronics and solid polymer electrolytes. Since a wide variety of cation–anion combinations can be used, it is useful to evaluate the impact of different anion and cation structures on the properties of plasticized starch to select the most suitable ionic liquid for each specific application. In this work, starch films plasticized with imidazolium-based ionic liquids were prepared by the solution casting method. 1-Ethyl-3-methyl imidazolium was chosen as a cation and the effect of different anions such as [SO4Et]−, [N(CN)2]−, [OAc]−, and [Cl]− on the film properties was investigated. In addition, a dicationic structure, consisting of two closely bonded imidazolium rings, was also considered. The characteristics of the corresponding starch-based films were analyzed and compared with those of films prepared with monocationic ionic liquids.

“…With the aim to embed CNTs in a polymeric electrolyte, good candidates were searched among biopolymers, finding that cellulose, starch, chitosan, agar, pectin and gelatin are good options [23]. For example, solid electrolytes based on polymeric pectin are used for the storage of anionic polysaccharide and ammonium iodide salt, exhibiting their maximum ionic conductivity (4.5 × 10 −3 S/cm) at room temperature [24]. Similarly, a polymeric electrolyte based on corn starch with different percentages of sodium bisulfite (NaHSO 3 ) shows an ionic conductivity of 2.22 × 10 −4 S/cm at room temperature [25].…”

This work reports on membranes of a combination of chitosan–starch with lithium-modified multiwall carbon nanotubes. One of the most important contributions of this article is the functionalization of the surface of multiwall carbon nanotubes by means of an accessible technique that allows for high grafting yields of lithium and their incorporation into a polymeric matrix. The natural compounds chitosan and starch were used as a support to embed the nanotubes, forming membranes with good mechanical stability. A thorough characterization via Raman, infrared and X-ray photoelectron spectroscopies, transmission and scanning electron microscopies and dynamic mechanical analysis is presented here, as well as electrochemical characterization. The composition, structure and mechanical stability of the membranes make them viable candidates to be used as anodes sustainable Li-ion batteries.
