Special Issue Information

Dear Colleagues,

Wood plays a crucial role in tackling climate change as it acts as a carbon sink, sequestering carbon dioxide from the atmosphere, and the field of wood processing and modification is currently undergoing dynamic changes, marked by continuous advancement, innovation, and evolving techniques. This Special Issue aims to explore the dynamic transformations that wood undergoes post-processing and -modification, shedding light on the multifaceted alterations in its properties and characteristics. From novel processing methods enhancing wood's structural integrity to innovative modification techniques improving its durability and functionality, this Special Issue seeks to unravel the dynamic nature of wood materials in response to changing methodologies and technologies. By compiling cutting-edge research and insights, the aim is to provide a comprehensive understanding of the dynamic changes shaping the landscape of wood processing and modification.

Potential Topics:

  • Changes in wood properties post-processing and -modification;
  • Advanced techniques in wood processing for enhanced outcomes;
  • Innovative wood modification methods for improved characteristics;
  • Responses of wood to novel processing technologies;
  • Improving wood durability through innovative modification approaches;
  • Adapting wood properties to meet evolving industry demands;
  • Alterations in wood structure and composition following processing and modification;
  • Harnessing transformations in wood for sustainable manufacturing practices;
  • Optimizing wood processing and modification techniques.

The goal of this study is to comprehensively evaluate the natural weathering performance of three wood species representing hardwood and softwood modified with the acetylation process. Alder (Alnus glutinosa L.), beech (Fagus sylvatica L.), and radiata pine (Pinus radiata D. Don) were characterised by various techniques to determine the aesthetical, chemical, and physical changes. The overall aesthetic performance of the investigated species was similar, with all showing a change in appearance after 9 months of exposure. However, the multi-sensor approach used for characterisation revealed differences in weathering behaviour related to surface erosion, wettability, and changes in chemical composition between the investigated species. An increase in the surface roughness observed for both hardwoods was associated with the erosion of the wood surface and the leaching of photodegraded chemical components. On the contrary, values of Sa remained relatively constant for acetylated radiata pine. Acetylated pine wood exhibited lower susceptibility to bleaching at the initial stage of the weathering process (3 months) and represented a more constant CIE L* compared to the investigated hardwood species. The contact angle measured with water gradually decreased in the case of acetylated radiata pine for up to six months, then it plateaued with a slight oscillation around 15°. For both hardwood species, the big drop was observed already after three months, followed by rather similar values. The PCA of IR spectra highlighted different mechanisms in the weathering of acetylated softwood and hardwood. The acetylated hardwood samples showed higher thermal stability than acetylated radiata pine. Experimental findings provide a comprehensive understanding of the long-term performance of acetylated wood, which directly influences its practical applications by enhancing design strategies, maintenance planning, product development, market acceptance, and overall sustainability. Performed tests have demonstrated the potential of underutilised hardwood species, enhanced through the acetylation process, to serve as alternative cladding materials to commonly used acetylated radiata pine.
