Overview

Experiments demonstrate plasma etching creates hydrophobic super-black wood, indicating potential for sustainable materials.

Key Points

  • This research aims to explore the creation of super-black wood using high-energy plasma etching techniques.
  • Used inductively coupled oxygen plasma for surface modification of basswood and other species.
  • Conducted reflectivity and color measurements with UV-Vis-NIR spectrophotometer and color spectrophotometer.
  • Analysed structural changes with scanning electron microscopy and X-ray micro-computed tomography.
  • Evaluated chemical changes using FTIR-spectroscopy.
  • Achieved an average reflectivity of 0.68% in plasma-etched basswood surfaces.
  • Created a lignin-enriched surface with unique structural features.
  • Confirmed super-black characteristics in jelutong and European lime; species without these features did not achieve super-black properties.
  • Demonstrated hydrophobic properties in super-black basswood, which were preserved after epoxy treatment.
