Based on the unique ability of defibrillated sepiolite (SEP) to form stable and homogeneous colloidal dispersions of diverse types of nanoparticles in aqueous media under ultrasonication, multicomponent conductive nanoarchitectured materials integrating halloysite nanotubes (HNTs), graphene nanoplatelets (GNPs) and chitosan (CHI) have been developed. The resulting nanohybrid suspensions could be easily formed into films or foams, where each individual component plays a critical role in the biocomposite: HNTs act as nanocontainers for bioactive species, GNPs provide electrical conductivity (enhanced by doping with MWCNTs) and, the CHI polymer matrix introduces mechanical and membrane properties that are of key significance for the development of electrochemical devices. The resulting characteristics allow for a possible application of these active elements as integrated multicomponent materials for advanced electrochemical devices such as biosensors and enzymatic biofuel cells. This strategy can be regarded as an “a la carte” menu, where the selection of the nanocomponents exhibiting different properties will determine a functional set of predetermined utility with SEP maintaining stable colloidal dispersions of different nanoparticles and polymers in water.

The resulting nanohybrid suspensions could be easily conformed either as films or as foams, where each individual component plays a critical role in the biocomposite: HNT acts as nanocontainer for bioactive species, GNP provide electrical conductivity (enhanced by doping with MWCNT) and, the CHI polymer matrix introduces mechanical and membrane properties, which are of key significance for the development of electrochemical devices. The resulting characteristics open the way to use these active elements as integrated multicomponent materials for advanced electrochemical devices such as biosensors and enzymatic biofuel cells. This strategy can be regarded as an “a la carte menu”, where the selection of the nanocomponents provided with diverse properties will determine a functional set of predetermined utility thanks to the SEP behavior to maintain stable colloidal dispersions of different nanoparticles and polymers in water.

“…This is the most variable component to be studied because a large variety of fillers has been used so far. Especially for EFCs, the conductive nanofillers for inks are represented by carbon nanomaterials, e.g., graphene, carbon nanotubes, carbon nanosheets, carbon nanowires/fibers, etc., [213][214][215] or conductive functionalized polymers, e.g., poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT: PSS), polyethyleneimine (PEI), polypyrrole (PPy), and polyindole [198,[216][217][218]. The first ones have very high conductivity, mechanical resistance, and highcost, while the latter have low cost, softness, flexibility, easy manipulation, and good conductivity.…”

Next-generation wearable technology needs portable flexible energy storage, conversion, and biosensor devices that can be worn on soft and curved surfaces. The conformal integration of these devices requires the use of soft, flexible, light materials, and substrates with similar mechanical properties as well as high performances. In this review, we have collected and discussed the remarkable research contributions of recent years, focusing the attention on the development and arrangement of soft and flexible materials (electrodes, electrolytes, substrates) that allowed traditional power sources and sensors to become viable and compatible with wearable electronics, preserving or improving their conventional performances.
