Special Issue Information

Dear Colleagues,

Bio-based materials such as wood, bamboo and their composites have attracted attention among researchers due to their eco-friendly nature. Moreover, their products have been used in daily life, such as in furniture, construction and even aerospace. However, owing to the drawbacks of natural polymers in cell walls, their applications undergo various challenges. Surface modification and protection can overcome the defects and even endow the bio-based materials with multi-functions, such as dimensional stability, hydrophobicity, anti-fungal properties and flame retardance. Many kinds of modification techniques have been reported to achieve the target in which the improvement on overall performances is expected. Driven by the current development state of ideas and techniques on modification, it is necessary to understand the mechanism of the modification and protection process. Further, we welcome papers that explore potential ideas for modification and protection.

This Special Issue will serve as a forum for papers focusing on the following concepts:

  • Eco-friendly methods for the modification and protection of bio-based materials.
  • Modification and protection with multi-functions.
  • Experiments with new methods or characterizations on surface modification and protection.
  • The development of mechanisms for the modification and protection of bio-based materials.
  • Advanced materials preparation and characterization made from bio-based materials.

Bamboo scrimber refers to a lignocellulosic structural material, which is usually attacked by water, ultraviolet radiation and fungus. Surface coating is an effective way to protect it, and its coating properties depend on surface wettability. In this study, the surface wettability of bamboo scrimbers with varying resin content was investigated via the comprehensive analysis of surface roughness, surface contact angle, surface free energy, surface chemical composition and coating properties. The resultant scrimbers had a similar profile with low roughness. Their surface was hydrophilic, but the hydrophilicity decreased with the increase in resin content. High resin content gave rise to low total free energy, in which the Lifshitz–van der Waals component was dominant and it decreased with the increasing resin content. Meanwhile, the ratio of the electron-accepting component to the electron-donating component becomes higher. This was due to the decreasing hydrophilic groups (e.g., -OH and -COOH groups) and the increasing oxygen-free groups (e.g., C-H and -CH2 groups) on the scrimber surface. The resin content affected the adhesion by decreasing the surface wettability, but the coating adhesion still reached the level of 2 for all bamboo scrimbers. The results will provide a theoretical reference for the surface coating of bamboo scrimbers in the structural application for good coating durability. Full article
