Abstract: 
This study provides a comprehensive review of contemporary research and characterization techniques for nanocomposites, along with a thorough analysis of the latest trends in this field. Nanocomposites represent a novel category of material, characterized by the presence of fillers with a nanoscale dimension (graphene 5-25 nm, nano silica 70-90 nm). These materials possess considerable potential for application in diverse industrial sectors, including the automotive, aerospace, construction, electrical, and food packaging domains. There is a substantial interest in the utilization of nanoparticles, such as graphene and nano-silica fillers, in the development of innovative natural composites. The possibility of obtaining environmentally friendly nanocomposite materials with improved properties based on renewable natural raw materials (wood flour), which are easy to obtain and inexpensive, as well as nanoparticles as important fillers in polymer composites, is demonstrated. A range of composite materials has been developed, based on wood flour, with varying dispersion qualities, and with different percentage contents of binder (3-20%), ethyl silicate (40%), as well as nanofillers, including graphene and nano-silica particles. It has been demonstrated that the addition of nanoparticles enhances the mechanical properties and overall performance of the composites. In order to identify the composition of the nanocomposites, a series of Fourier transform infrared spectroscopic studies was carried out. The physical-mechanical properties and water absorption of the compositions were studied, and surface morphology was investigated using the optical microscopic method. In addition, thermogravimetric analysis methods were used to observe the thermal properties of the materials.
