Abstract
Diffuse reflectance Fourier transform infrared spectroscopy (DRIFT), solid state cross-polarization/magic-angle-spinning 13C-nuclei magnetic resonance spectroscopy (CP/MAS 13C-NMR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and thermomechanical analysis (TMA) were used in this study to elucidate the characteristics of wood sawdust after esterification. Results revealed that thermoplastic wood was produced by solvent-free esterification using octanoyl chloride. Increasing the duration of treatment enhanced the extent of esterification. After octanoylation, the crystallinity of wood sawdust was decreased, whereas thermoplasticity, hydrophobicity, and thermal stability were enhanced. The complete flow of the octanoylated wood meal was achieved at around 300°C under a force of 0.01 N, indicating that octanoylated wood sawdust is a good thermoplastic material.
