Conductive Silk‐Based Composites Using Biobased Carbon Materials (original) (raw)
There is great interest in developing conductive biomaterials for the manufacturing of sensors or flexible electronics with applications in health-care, tracking human motion, or in-situ strain measurements. These biomaterials aim to overcome the mismatch in mechanical properties at the interface between typical rigid semiconductor sensors and soft, often uneven biological surfaces or tissues for in vivo and ex vivo applications. In this paper we demonstrate the use of biobased carbons to fabricate conductive, highly stretchable, flexible and biocompatible silk-based composite biomaterials. Biobased carbons are synthesized via hydrothermal processing, an aqueous thermochemical method that converts biomass into a carbonaceous material that can be applied upon activation as conductive filler in composite biomaterials. We combine experimental synthesis and full-atomistic molecular dynamics modeling to synthesize and characterize these conductive composite biomaterials, made entirely from renewable sources and with promising applications in fields like biomedicine, energy, and electronics.
