AB  - Nanocellulose constitutes promising resources for next-generation electronics, 
      particularly when incorporated with conductive polymers due to their abundance, 
      renewability, processability, biodegradability, flexibility, and mechanical 
      performance. In this study, electrically conducting cellulose nanofibers were 
      fabricated through in situ chemical polymerization of 
      poly(3,4-ethylenedioxythiophene) (PEDOT) on the surface of sulfuric acid-treated 
      cellulose nanofibers (SACN). The utilization of highly crystalline SACN extracted 
      from tunicate yielded synergistic effects in PEDOT polymerization for achieving a 
      highly conductive and molecularly uniform coating. Polymerization parameters, 
      such as monomer concentration, molar ratio with oxidants, and temperature, were 
      systematically investigated. High electrical conductivity of up to 57.8 S cm(-1) 
      was obtained without utilizing the classical polystyrenesulfonate dopant. The 
      resulting nanocomposite demonstrates the unique advantages of both electrically 
      conductive PEDOT and mechanically robust high-crystalline cellulose nanofibers. 
      As a proof-of-applicational concept, an electrical circuit was drawn with 
      SACN-PEDOT as the conductive ink on flexible paper using a simple commercial 
      extrusion-based printer. Furthermore, the flame-retardant property of SACN-PEDOT 
      was demonstrated owing to the high crystallinity of SACN, effective char 
      formation, and high conductivity of PEDOT. The multifunctional SACN-PEDOT 
      developed in this study shows great promise to be employed in versatile 
      applications as a low-cost, ecofriendly, flexible, and sustainable electrically 
      conductive material.
