The use of nanoadditives and the development of nanotechnology in the production of composite materials opens up new opportunities for improving the production of building materials using wood and plant-based raw materials. This study highlights the impact of nanomodification processes on the chemical composition of plant-based fillers and, consequently, the performance properties of composite materials. This article examines the adhesive strength and cohesive interactions in organomineral binders. The surface tension of wood-based fillers and various binders is studied. It is found that the surface tension of binders is significantly higher than that of wood-based fillers, leading to bifurcation between the adhesive and substrate. The introduction of nanoadditives significantly reduces the surface and interfacial tension of liquids. It is hypothesized that nanoadditives in the organomineral binder act as stabilizers, preventing the binder from being absorbed more quickly into the fibers of the wood-plant filler, thereby increasing the binder's cohesion and the overall strength of the material. This hypothesis is supported by a study of the wetting of wood-plant filler by an organomineral binder containing various types of nanoadditives. The geometric "sessile drop" method was used to determine the contact angles for different types of filler and binder.
