“…The maximum water content (MWC) of model waterlogged wood samples increased significantly from 197.15 to 260.04%, while the basic density (BD) decreased from 0.36 to 0.32 g/cm 3 (Table S1). These results suggest that treatment with NaOH can significantly alter the major physical properties of wood samples. , Furthermore, Fourier transform infrared spectroscopy (FTIR) spectra analysis, presented in Table S2, ,,− revealed that the hemicellulose of model waterlogged wood samples was notably degraded, as illustrated in Figure S1a. , In contrast, cellulose (Figure S1b) and lignin (Figure S1c) were only slightly degraded.…”

“…Samples by Chemical Degradation. According to procedures outlined in previous studies, 36,37 the model samples were immersed in a 1% (w/v) NaOH solution at 60 °C for 70 days to reach a waterlogged and chemical degradation. Following this treatment, the samples were then soaked in deionized water until the pH reached 7.…”

Lignin is the most abundant component in archaeological waterlogged wood, making it a potential consolidant with high compatibility for historical wood conservation. However, its consolidation effect is limited by its low penetration into the wood. In this study, modified lignin nanoparticles (LNPs) were proposed for the first time as conservation materials for waterlogged archaeological wood. Two modified LNPs were prepared with low molecular weight, small size, and high solubility in ethylene glycol (EG) for consolidating waterlogged wood samples. These nanoparticles, hydrophilic aminated LNPs (ALNPs) and hydrophobic esterified LNPs (MALNPs), greatly improved the consolidation effect of waterlogged wood samples compared to LNPs. This was demonstrated by measuring their physical properties, dimensional stability, and mechanical properties. The surface color change was almost within the acceptable range for the human eye. We also discussed two different reinforcement mechanisms of ALNPs and MALNPs. ALNPs can form hydrogen bonds with hemicellulose/cellulose in the wood to strengthen the fragile wood cell wall, while MALNPs can fill the wood cell lumen to support the cell wall and prevent deformation during drying. Our work provides an approach of using biomaterials as consolidants for archaeological waterlogged wood and expands the use of lignin in this field.

“…A study by Broada et al [26] revealed that methyltrimethoxysilane (MTMS) can effectively encrust and cover the microstructure of WAW. Recent studies have confirmed that MTMS is also satisfactory in reducing the hygroscopicity of treated wood [27,28]. Since MTMS molecules are able to penetrate and form a uniform coating on the cell wall surface, the pore area of WAW can be filled effectively.…”

To ensure the conservation of waterlogged archaeological wood, sustainable, safe, and effective methods must be implemented, with consolidation and dehydration being crucial for long-term preservation to maintain dimensional stability and structural integrity. This study compares the permeability of 45% methyltrimethoxysilane (MTMS) and 45% trehalose solutions to evaluate the dimensional changes, hygroscopicity, and mechanical properties of treated wood. Since the collected samples (from an ancient ship, Luoyang Canal No. 1) were mildly degraded, the drying method had a slight impact on the properties of archaeological wood. Consolidated with trehalose and MTMS agents, the longitudinal compressive strength of the waterlogged wood’s cell walls increased by 66.8% and 23.5%, respectively. Trehalose proved to be more advantageous in filling pores and reducing overall shrinkage, while MTMS significantly reduced the hygroscopicity and surface hydrophilicity of the wood substance. Overall, the MTMS treatment has a smaller effect on the appearance of samples, making it more suitable for the consolidation of mildly degraded waterlogged archaeological wood.

“…Silicon compounds are synthetic molecules widely used in wood protection due to their unique bifunctional structure and specific reactivity [5]. They have been utilized for the preservation and conservation of wood and wood-based products, as well as additives for preservatives, with the aim of improving weathering performance, reducing wood hydrophilicity, decreasing flammability, and enhancing decay resistance [6][7][8].…”

Wood is very susceptible to the action of biotic agents. There is a growing interest in the protection of wood and wood artworks to extend their life, using environmentally friendly preservatives. The aim of this paper was the study of nano/siliconate impregnation system for wood protection to control biological colonization. The biotic agents studied have been wood decay fungi. In conclusion, this paper has shown that all the treatments have presented an excellent protective performance against biotic agents. Is important to mention that a synergistic effect can be observed when generating the siliconate/nanoparticle mixtures, resulting in protective systems with excellent efficiency for all the degrading agents. Moreover, it presents an easy application, which represents not only a watertight protective system, but also a set of systems that may be used and managed according to the availability of the active components, the costs, and, most importantly, without having to modify the form of application.
