Abstract: Using Balsa wood as raw material, lignin was removed, and the acrylic acid solution was impregnation and cured to get transparent wood. Subsequently, FeCl₃ solution was further impregnated to form a flexible FeCl₃/polyacrylic acid transparent conductive wood. Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscopy(SEM) were used to characterize these materials. The results showed that the transparent wood had the best conductivity when it was immersed in 0.75% FeCl₃ solution for 60-70 min. The tensile strength of transparent wood soaked in 0.5 mol/L FeCl₃ solution could reach 6.03 MPa, which was nearly 10 times higher than that of the unsoaked transparent wood(0.55 MPa). In addition, the resistance sensing performance of transparent wood was excellent, and it showed characteristic electrical changes correlated with the different human actions, which demonstrated the potential applications in conductive films, flexible human sensors and other fields.
