“…1-ethyl-3-methylimidazolium formate is highly selective towards the dissolution of hemicellulose [ 89 , 90 ]; as pretreatment media for wood biomass to improve the accessibility of the cellulase enzymes in the bulk of the wood [ 91 ]; as media for the cellulose component chemical modification, e.g., acetylation of wood in and 1-ethyl-3-methylimidazolium chloride/acetate mixture [ 92 ]; as media for obtaining useful chemicals through depolymerization of wood lignin (5-hydroxymethylfurfural can be obtained after a long-run 24 h thermal treatment of wood 1-ethyl-3-methylimidazolium chloride) or wood cellulose (maltose, nigerose, kojibiose, laminaribiose, isomaltose, and gentiobiose can be obtained from cellulose through treatment with 1-ethyl-3-methylimidazolium chloride) [ 93 , 94 ]; as carriers for different impregnants or antifungal agents into the structure of wood. In this application, ILs are useful through improving the penetration ability of the transported species through promoting wood swelling [ 25 , 33 ]; as plasticizers for wood: ionic liquids with alkylammonium, alkylpyridinium or 1- n -alkyl-3-methylimidazolium (>C10) cations, do not dissolve the wood components, but can disrupt the inter- and intramolecular bonding in cellulose and/or lignin and increase the number of amorphous domains in opposition with the crystalline ones [ 30 , 95 ]; as additives, providing various functionality: fire retarders (especially alkylphosphonium ILs, or ILs with hexafluorophosphate or tetrafluoroborate anions) [ 96 ], thermal and UV stabilizers [ 29 , 97 ], antistatic agents [ 98 ] and so forth. …”

Ionic liquids represent a class of highly versatile organic compounds used extensively in the last decade for lignocellulose biomass fractionation and dissolution, as well as property modifiers for wood materials. This review is dedicated to the use of ionic liquids as antifungal agents for wood preservation. Wood preservation against fungal attack represents a relatively new domain of application for ionic liquids, emerging in the late 1990s. Comparing to other application domains of ionic liquids, this particular one has been relatively little researched. Ionic liquids may be promising as wood preservatives due to their ability to swell wood, which translates into better penetration ability and fixation into the bulk of the wood material than other conventional antifungal agents, avoiding leaching over time. The antifungal character of ionic liquids depends on the nature of their alkyl-substituted cation, on the size and position of their substituents, and of their anion. It pertains to a large variety of wood-colonizing fungi, both Basidiomycetes and Fungiimperfecti.

“…In recent years, various nanomaterials have been widely used to improve the properties of waterborne polyurethane coating formulations because they have a large effect despite their small size [23]. The nanoadditives in wood flooring coatings improve their resistance properties [24,25], but they can also strongly influence other physical and mechanical properties of free films [26,27].…”

Parquet flooring is one of the most common types of flooring, the surface of which can be covered with various coatings. To avoid possible damage to the parquet during use, it is necessary to test the surfaces before installation according to various non-standard and standard protocols. The present study provides an overview of the interactions between the properties of selected waterborne coatings (solids content, hardness, resistance to cracking, tensile strength) and the properties of oak wood flooring surfaces (dry film thickness, coating adhesion, resistance to scratching, impact, abrasion and cold liquids). The tests conducted showed that the performance of the surface systems was highly dependent on the coating formulations, as they were either one- or two-component systems. Although no major differences in surface resistance to cold liquids were found, there was a correlation between coating thickness, hardness and tensile strength. The harder coatings had higher tensile strengths and lower elongations. The coatings with higher tensile strength and better hardness achieved better adhesion properties. The coatings that exhibited ductile behavior showed the worst scratch resistance. A statistically significant relationship was found between the higher resistance of the flooring systems to impact stress and the improved abrasion resistance. The obtained results provide potential end users of surface coatings with valuable information on the quality that can be expected in wood flooring.

“…Recently, ionic liquids (ILs) have been considered to be next-generation antistatic agents, owing to their high ionic conductivity and low resistivity, even under dry conditions. − IL materials have produced remarkable influences in various application fields using 3D printing, such as electron devices and biological materials . For example, Gatenholm et al reported 3D bioprinting inks composed of a tailored design of regenerated cellulose and different ILs to produce small-featured structures .…”

With the development of 3D printing technology, the desire to apply this technology in terminal part manufacturing is becoming increasingly urgent. Therefore, the performance and functional requirements of 3D printing materials are constantly evolving. Here, we have designed 3D photoprintable inks based on a polymerizable deep eutectic solvent (DES) combining acrylic acid (AA) and choline chloride (ChCl). The photocurable inks show fast curing speeds that were confirmed by real-time studies, and the printed parts have moderate strength and relatively good flexibility due to the addition of AA/ChCl-type DESs. Moreover, the addition of AA/ChCl endows the printed object with an excellent permanent antistatic effect, demonstrating that the surface resistivity of printed films is reduced to 106–10 Ω with different amounts of AA/ChCl. The antistatic effect is also maintained with low temperature (−15 °C), long storage time, and repeated alcohol surface washing. Furthermore, we have successfully printed various complicated transparent objects, indicating that AA/ChCl is uniformly embedded into the polymer network. We believe that the introduction of polymerizable DESs into 3D photoprintable inks provides a low-cost strategy for fabricating transparent, permanent, and stretchable antistatic materials for various applications.
