A fiber is provided as a substrate for a functional nanostructure (coated fiber), composed of (a) a fiber substrate; (b) a reactive dye conjugating moiety covalently bound to the fiber substrate; (c) a bonding agent covalently bound to the reactive dye conjugating moiety; and (d) the functional nanostructure bound to the bonding agent. A method of making the coated fiber is also provided, involving the following steps in any order: covalently binding the reactive dye conjugating moiety to the fiber; covalently binding a bonding agent to the reactive dye conjugating moiety; and binding the functional nanostructure to the bonding agent. The nanostructures are tenaciously attached to the fibers, resisting very rough treatments, and can be made using inexpensive and widely available reactive dyes under non-stringent synthesis conditions.

Compositions and methods related to conducting polymeric compositions that can be used for the storage of electrical energy are generally provided. In some embodiments, the composition comprises redox active polymers comprising an electrophilic nitrogen containing heterocycle and an electron rich aromatic compound. In some embodiments, the composition comprises a triazine-based polymer. The electroactive polymers may be formed, in some cases, by polymerizing an electrophilic nitrogen containing heterocycle-based unit with an electron rich aromatic compound in the presence of heat and an acid-based catalyst. The resulting electroactive polymers may be suitable as polymer films for use as electrodes in energy storage devices. The polymer films disposed as electrodes can improve the energy density of such devices.

A mixture can be used for modifying the rheology of polymeric substrates. The mixture contains a hydroxylamine ester and an isocyanate functionalized with a thio compound.
