Abstract This study investigates the effects of pristine and acetylated nanofibrillated cellulose (NFC) a poly(lactic acid)‐ co ‐poly(butylene succinate) (PLA‐ ‐PBS) compatibilizer on PLA/PBS 80/20 blends. Pristine or NFC (1 wt%) were incorporated into blends using masterbatches.

Wood, a vital material for both modern and heritage objects, is particularly susceptible to degradation caused by water due its hydrophilic nature porous structure. Therefore, developing sustainable strategies protect wood of significant importance. This study aims produce highly hydrophobic coating the protection following straightforward procedure using materials that are compatible with wood. First, nano/sub-microlignin (NL) isolated produced from beech through one-step tailored organosolv process. Next, NL incorporated into Sivo 121, water-borne solvent-free silane system recommended manufacturer protecting surfaces. Composite coatings containing various concentrations 121 applied chestnut (Castanea spp.) oak (Quercus spp.). The impact concentration on contact angles drops (CAs) colour changes (ΔE) treated specimens investigated. 4% w/w demonstrates enhanced hydrophobicity (CA = 145°) has negligible effect pristine (ΔE < 3). wetting properties coated not affected after 100 tape peeling cycles. However, exhibits poorer performance chestnut, i.e., CA 135°, which declines 80 cycles, ΔE > 5. drop pH does have any noticeable CA. latter remains stable even prolonged exposure samples artificial UV radiation outdoor environmental conditions. Finally, composite offers good comparable species in biological durability soil burial test
