“…Fully sustainable wood modification, in other words, new generation modification systems can be provided by using energy efficient processes, using non‐toxic, bio‐based and biodegradable chemicals, and causing no waste at the end of its service life 3,7 . In recent publications on innovative wood modification techniques, the researchers usually focus on using natural compounds, bio‐based, renewable or biodegradable polymers such as flavonoids, poly(ε‐caprolactone) (PCL), 4,4′‐azobis‐4‐cyanopentanoyl chloride (ACPC) bearing acyl chlorides, in situ styrene polymerisation after treatment of methacryloyl chloride and methacrylic anhydride, low‐molecular‐weight oligomers of poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(butylene succinate) (PBS), and poly(butylene adipate) (PBA), polyglycerol succinate, sorbitol, citric acid, extractives, plant oils, waxes, natural resins, chitin, chitosan, starch, gelatin and zein, etc 8–19 .

Increasing environmental pressures over the last few years have led to attention for non‐biocide treatments in the wood protection field. The ε‐caprolactone modification of wood by substitution or blocking of hydroxyl groups with hydrophobic poly(ε‐caprolactone) (PCL) is one of the novel modification methods developed in recent years. In this study, ring‐opening polymerisation of ε‐caprolactone in wood cell walls was evaluated by the third and sixth re‐use of recovered monomer and by oven‐curing method. Spruce samples were modified by re‐used ε‐caprolactone and exposed to the natural weathering agents for 12 months. After weathering, the colour change, surface roughness measurements, and macroscopic and ultra‐microscopic observations revealed that the modified wood had better surface properties than reference wood. Fourier‐transform infrared (FTIR) analysis proved that PCL could be found on the weathered surface up to the sixth month, but very little amount was detected on the surfaces with a longer weathering period. The results clearly showed that the efficiency of PCL modification with re‐use of the monomer solution was sufficient during the initial weathering periods, but efficiency was reduced after a prolonged exposure period.

“…The color is also an important feature to be studied during the wood weathering since the weathering of wood causes photodegradation. The CIELAB color measuring system has been widely employed to study the color change in wood under UV radiation [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. The color was considered as an informative parameter to monitor the wood photodegradation [ 43 ].…”

Color parameters were used in this study to develop a machine learning model for predicting the mechanical properties of artificially weathered fir, alder, oak, and poplar wood. A CIELAB color measuring system was employed to study the color changes in wood samples. The color parameters were fed into a decision tree model for predicting the MOE and MOR values of the wood samples. The results indicated a reduction in the mechanical properties of the samples, where fir and alder were the most and least degraded wood under weathering conditions, respectively. The mechanical degradation was correlated with the color change, where the most resistant wood to color change exhibited less reduction in the mechanical properties. The predictive machine learning model estimated the MOE and MOR values with a maximum R2 of 0.87 and 0.88, respectively. Thus, variations in the color parameters of wood can be considered informative features linked to the mechanical properties of small-sized and clear wood. Further research could study the effectiveness of the model when analyzing large-sized timber.
