“…Currently, much attention is paid to the investigation of thermoplastic composites based on natural fillers [ 1 , 2 , 3 ]. Manufacturers of such composites increase their production volumes from year to year, as well as the range of their applications, due to their demand and declining ecological situation.…”

The work presents the results of a comprehensive study on obtaining compositions based on polypropylene and natural fillers modified by enzymatic preparations under high-shear forces. The experiment protocol includes determining the modification time and the ratio of water volume to the mass of natural filler (hydro modulus) during modification, which turned out to be different for each type of filler. Physical and mechanical analyses were conducted to evaluate the operational characteristics of the obtained composites, with particular attention given to comparing the modified compositions with their unmodified counterparts. The time and hydro module of the enzymatic modification of the natural fillers under consideration were investigated, which turned out to be different for each type of filler. It was found that surface modification of natural fillers improves mechanical properties; namely, the tensile strength of composites with wood and sunflower fillers increases by 10%, and the impact viscosity of composites also increases by 12% with wood and sunflower fillers. Water absorption decreases in composites, after 2 h boiling, with wood flour by 30% and with rice husk by 10%. After a 14-day test at room temperature, water absorption decreases by more than 30% in composites with rice husk. When determining the free surface energy of composites, it was found that the modification of the filler reduces the polarity of the composites in all samples, which can be interpreted as an improvement in the interaction between the filler and the polymer matrix. The findings of this research have important implications for the development of advanced polymeric materials that can be used in a wide range of applications, including automotive, aerospace, and construction industries. The results underscore the importance of surface modifications to optimize the properties of polymeric composites and provide valuable insights into the role of natural fillers in enhancing the performance of these materials.

Powder lignocellulose modifiers for vulcanized rubbers were prepared from secondary paper resources (recycled cardboard) treated with TiCl4 in hexane. The diffraction patterns, IR spectra, and morphological characteristics of the materials obtained, including the geometric characteristics and length distribution of fibers, were analyzed. The content of titanium, lignin, and carbonyl and carboxyl groups and the bulk density of the material were determined. The presence of up to 5 wt parts of powder modifiers per 100 wt parts of rubber in the rubber stock favors preservation of physicomechanical properties of vulcanized rubbers both before and after accelerated thermal oxidative aging at 100°C for 72 h, enhancing the resin–metal cord adhesion and thus prolonging the operation life of the vulcanized rubbers.
