Starch modified with silanes – high hydrophobic surface treatment for wood protection
2023 - IRG/WP 23-40981
The great potential of silanes for starch modification and their utility as surface wood protection is still not sufficiently assessed. The work aimed to analyze the crosslinking process's effect on starch modification with silane and tested the hydrophobic properties of surface-treated wood. The starch treatment was modified with methyltrimethoxysilane or N-octyltriethoxysilane. SEM-EDX with a cr...

Surface treatment of cross-laminated timber to improve water repellency and UV resistance
2024 - IRG/WP 24-20716
Cross-laminated timber (CLT) has emerged as a revolutionary building material, offering a sustainable alternative to traditional construction methods. By layering and bonding multiple layers of wood at right angles, CLT creates a robust and versatile structural element capable of supporting significant loads while promoting eco-friendliness and design flexibility. However, despite its numerous adv...

Natural weathering of modified pine and Eucalyptus woods by surface charring
2024 - IRG/WP 24-30801
Within various wood modification techniques, surface charring is anticipated to extend the lifespan of wooden components in building facades; however, visual deterioration of charred cladding materials has become a notable concern. This study, conducted through international collaboration, aimed to assess the resistance of bio-based facade materials to weathering in the Turkish climate. The natura...

A novel treatment for increasing UV stabuility of wood based on citric acid and urea
2024 - IRG/WP 24-30811
Wood, a fundamental material in the Built Environment, faces challenges related to durability and weathering, notably UV degradation leading to colour changes. This study explored a novel treatment method utilising citric acid and urea to enhance the UV stability of wood. The reaction between these compounds forms fluorescent species and insoluble nanoparticles upon thermal treatment. Two treatmen...

Changes in decay risk of wood in ground contact over Europe, from analysis of historic climate conditions
2024 - IRG/WP 24-41008
Changing climate conditions will affect global temperature and precipitation patterns, shifting some geographical areas into states that are more suitable for fungal wood decay. Climate normals, which are taken over a 30-year period, capture vast spatial and temporal variations in these conditions and comparing these can show changes over time. Importantly, being able to identify locations that ha...

Functionalization of wood with nano-sized titanium dioxide – Efficacy against mould growth and effect on cell wall integrity
2025 - IRG/WP 25-20740
Nano-sized titanium dioxide (nano TiO2) is a photocatalytic compound that generates reactive radicals under UV radiation, which can inhibit microbial growth and impart self-cleaning properties. This effect has been widely utilised on materials such as glass or tiles. This study investigates the potential of nano TiO2 treatments to prevent mould growth on wood and their impact on cell wall integrit...

Plasma Modification of Basswood Creates Super-Black Wood
2025 - IRG/WP 25-30826
A super-black wood with low reflectivity in the UV/Vis range is created by plasma modifying transverse basswood surfaces. Here the super-black wood is characterised, the process used to make it is described and its possible practical uses are discussed. Wood samples are exposed to oxygen glow-discharge plasma. Transverse surfaces exposed to high-energy plasma have a deep-black velvety appearance. ...

Introduction of UV absorbers to wood surfaces via atom transfer radical polymerization
2025 - IRG/WP 25-30834
Wood is a promising material suited for both residential and commercial construction. However, the structure of the wood materials varies depending on the environmental factors such as microorganisms, water, and light. In particular, wood surfaces exposed to outdoor conditions are rapidly degraded because cell wall chemical components such as lignin structure strongly absorb ultraviolet (UV) light...
