Abstract: The increasing incidence of wildfires has resulted in a substantial accumulation of wildfire-charred wood, most of which remains underutilized.This study investigated the potential of carbonized wood as a conductive material by fabricating conductive paper using wood carbonized at 1,000°C for 1 hour and multi-walled carbon nanotubes (MWCNTs).FE-SEM analysis showed that a higher content of charred wood resulted in irregular particle formation, disrupting the MWCNT network.FT-IR analysis confirmed modifications in functional groups, while surface resistance measurements showed increased electrical resistance and reduced electrical conductivity with higher charred wood content.However, additional dip coating cycles improved electrical conductivity by improving material contacts and electron transport pathways.These results indicate that wildfire-charred wood is a promising candidate for conductive applications and provide valuable insights into optimizing material composition for improved performance.
