TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The gel matrix is formed from gelating agent chosen from hydroxy-substituted organic compound, polysaccharide, dipeptide, protein, polymer, carbon nanotubes, non-doped or doped graphene, functionalized silica nanospheres, and silica sol-gel. The gelating agent is polymer, and the polymer is chosen from poly(vinylidene fluoride-co-hexafluoropropylene). Preferred Process: Preparation of assembly involves combining a gelating agent with an ionic liquid at preset temperature to produce a mixture, and allowing the gelating agent to set and thereby form a gelated ionic liquid film in which the ionic liquid is encapsulated, and contacting the mixture or the gelated ionic liquid film with an electrically conductive surface, and in which the mixture is contacted with the electrically conductive surface before allowing the gelating agent to set, contacting the mixture or the gelated ionic liquid film with the electrically conductive surface which is effected by printing the mixture onto the electrically conductive surface, providing gelated ionic liquid film (F3) comprising encapsulated ionic liquid (L3) in contact with electrically conductive surface (S3), and contacting gelated ionic liquid films (20) and (F3).
