“…During the exposure of wood to the weathering outdoor agents, there are an active leaching process and removal of some wood components that generally cause an increase in surface roughness. Cracks and erosion on the sample surface also contribute to an increase in surface roughness 35 . Better surface properties of PCL‐modified wood were probably due to the inhibition of the removal of cell wall components by polymer moieties, which led to better surface roughness.…”

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.

Wood modification is now widely recognized as offering enhanced properties of wood and overcoming issues such as dimensional instability and biodegradability which affect natural wood. Typical wood modification systems use chemical modification, impregnation modification or thermal modification, and these vary in the properties achieved. As control and understanding of the wood modification systems has progressed, further opportunities have arisen to add extra functionalities to the modified wood. These include UV stabilisation, fire retardancy, or enhanced suitability for paints and coatings. Thus, wood may become a multi-functional material through a series of modifications, treatments or reactions, to create a high-performance material with previously impossible properties. In this paper we review systems that combine the well-established wood modification procedures with secondary techniques or modifications to deliver emerging technologies with multi-functionality. The new applications targeted using this additional functionality are diverse and range from increased electrical conductivity, creation of sensors or responsive materials, improvement of wellbeing in the built environment, and enhanced fire and flame protection. We identified two parallel and connected themes: (1) the functionalisation of modified timber and (2) the modification of timber to provide (multi)-functionality. A wide range of nanotechnology concepts have been harnessed by this new generation of wood modifications and wood treatments. As this field is rapidly expanding, we also include within the review trends from current research in order to gauge the state of the art, and likely direction of travel of the industry.
