Optimization via artificial intelligence of intumescent coatings for wood substrates
2023 - IRG/WP 23-40987
The development of new materials requires a large amount of experiments representing a major issue to innovate. This is particularly true for complex material formulations such as flame retarded materials that could contain a number of ingredients. Artificial Intelligence based optimization (more precisely Bayesian optimization) techniques appear to be efficient methods to optimize complex systems...

Enhancing UV resistance and decay resistance of wood by nanoparticle dispersed linseed oil nanoemulsion
2024 - IRG/WP 24-20706
Enhancing increasing demand for eco-friendly and cost-effective wood coatings and preservatives has led to the development of water-borne formulations and use of non-toxic and natural materials such as vegetable oils and waxes. The aim of this study was to improve the UV resistance and decay resistance of wood by nanomaterial dispersed linseed oil emulsions. Highly stable nanoemulsions of linseed ...

Terpene-based latex synthesis for exterior wood protection
2024 - IRG/WP 24-20715
Driven by challenges in raw material supply chains, the coatings industry is actively seeking biobased alternatives to enhance outdoor wood protection. This study aims to investigate the integration of biobased monomers into latex formulations, aligning with protocols applicable in industrial contexts. A semi-batch emulsion polymerization protocol was developed, designed to be scalable and meet es...

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...

Influence of plasma treatment on the coatability of wood primer with a topcoat for exterior use
2025 - IRG/WP 25-30828
The coatability of oil, or of solvent-borne alkyd resin wood primers with waterborne acrylic finish is the subject of much debate, but not much information can be found in the scientific literature on this topic. The aim of our study was therefore to evaluate the adhesion strength of the waterborne acrylic coating on oiled wood or wood with a solvent-based alkyd primer and to test the recoatabilit...

Quantitative Prediction of Latent Deterioration in Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41038
Wood coatings play a vital role in prolonging the lifespan of timber structures by protecting them from environmental degradation. However, conventional evaluation methods rely on visual inspections, which cannot detect latent deterioration before visible damage occurs. This study integrates attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy with partial least squares ...

Development of an Early Degradation Diagnosis Technology for Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41047
Accurately predicting the degradation state of wood coatings is challenging, and as the coating deteriorates, it becomes a major factor accelerating the degradation of the wood itself. In this study, we aimed to develop a diagnostic technology that combines mid-infrared spectroscopy and machine learning to assess latent coating degradation, which cannot be detected visually, and to enable appropri...
