In situ polymerisation of isoeugenol as a green consolidation method for waterlogged archaeological wood

Abstract: Waterlogged archaeological wood is often in need of consolidation prior to drying to prevent shrinkage and cracking of the object. There is a need for new greener materials (than for example polyethylene glycol) and methods for consolidation to be developed. The use of wood-based components could provide good interaction between the consolidant and the remaining wood structure and would also support a shift away from fossil fuel-based materials to those with more sustainable sources. Based on this, lignin-like… Show more

“…The alum salt replaced the remaining water in the wood cells and recrystallized immediately upon removal from the heat treatment, thereby rapidly preserving the shape of the wooden artefacts. However, there is increasing recognition that new and/or additional strategies are required for conservation of such waterlogged wooden artefacts and a variety of approaches are being investigated [53][54][55][56][57][58], including those involving the use of new consolidants that specifically interact with the longer-surviving lignin content of archaeological wood [59,60].…”

“…McHale et al ( 2016 , 2017 ) have been seeking to develop lignin replacements for the decayed wood using isoeugenols (monomer M ~ 160 Da, comparable to that of an amino-acid or carbohydrate residue) which are structurally very similar to lignins, built up from very similar monomer units (Fig. 2 c), but of lower molecular weight (low enough to be absorbed into the wood), but have to be made to polymerize in situ using a peroxidase in the presence of hydrogen peroxide H 2 O 2 .…”

“…In addition, these can sometimes result in a plastic appearance affecting the way the public view the artefacts. Therefore, more natural consolidants are now being investigated (Christensen et al 2015 ; McHale et al 2016 , 2017 ).…”
