Environment-Friendly and Two-Component Method for Fabrication of Highly Hydrophobic Wood Using...

Area of Science:

• Materials Science
• Wood Modification
• Surface Chemistry

Background:

• Wood's natural hydrophilicity limits its practical applications.
• Developing hydrophobic wood is crucial for enhanced durability and performance.
• Existing methods may not be environmentally friendly or scalable.

Purpose of the Study:

• To develop an environmentally friendly method for creating highly hydrophobic wood.
• To investigate the mechanism of a two-component packaging method for wood modification.
• To evaluate the properties of the modified wood, including hydrophobicity, dimensional stability, and resistance to fouling and UV radiation.

Main Methods:

• A two-component packaging method utilizing Poly(methylhydrogen)siloxane (PMHS) and an inhibitor.
• Detailed analysis of the assembly mechanism.
• Measurement of water contact angles on modified wood surfaces (radial and cross sections).

Main Results:

• Achieved high hydrophobicity with water contact angles of 139.5° (radial) and 152.9° (cross section).
• Resultant wood exhibited excellent dimensional stability.
• Modified wood demonstrated good anti-fouling and UV-resistance properties.
• The method was also applicable to functionalizing filter paper for oil/water separation.

Conclusions:

• The two-component packaging method effectively imparts high hydrophobicity and stability to wood.
• This eco-friendly approach offers a promising solution for wood modification.
• The method shows potential for broader applications, such as in oil/water separation technologies.
