lexible and foldable electronic components require materials that can retain their electrical conductivity even after hard
mechanical manipulations and multiple folding events. Such a material was realized with two different methods exploiting
the combination of all-biodegradable components (substrate and the polymer matrix) and graphene nanoplatelets (GnPs).
A fibrous cellulose substrate was sized with a biopolymer-GnPs conductive ink rendering it electrically conductive (sheet
resistance ≈10 Ω/sq). The obtained nanocomposites can be used as electrodes for surface electromyography and for terahertz
electromagnetic interference shielding. With a similar approach, a flexible cotton-GnPs conductive nanocomposite was
realized. This material addresses several drawbacks related to durability and washability of wearable electronics material.
Micro-cracks formed after repeated folding-unfolding events can be healed through a hot-pressing process. Such cotton based
conductive composites could find several applications in smart textile industry.
