“…One effective solution to the problem of compatibility is the introduction of special additives into the formulation, which enhance the compatibility of the components in polymer composites with natural fillers. For non-polar polymers, such as polypropylene, maleic anhydride-grafted polyolefins are widely used as a modification for compatibility [ 6 , 7 , 8 , 9 , 10 , 11 ]. There are also various methods of plasma surface modification for polyolefins [ 12 , 13 ], which, while expensive, is an environmentally friendly and versatile method.…”

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.

“…В работах [7][8][9] используют физические методы модификации, относящиеся к экспонированию полимерных композитов под действием излучений различной природы: радиоволн, ультрафиолета, потоков заряженных частиц. В работах [10][11] для увеличения прочностных характеристик полимерной композиции с растительными наполнителями используют различные модифицирующие добавкисополимеры, модифицированные малеиновым ангидридом, которые показали улучшение совместимости полимерной матрицы и древесного наполнителя, значительное улучшение прочности при разрыве и снижение водопоглощения.…”

The results of a study of mixing compositions based on polypropylene and vegetable fillers modified with an enzyme preparation are presented. During the experiment, the optimal modification time and the ratio of the volume of water to the mass of the vegetable filler during modification were determined. Physical and mechanical tests revealed that the composites with the modification were superior to the basic composites without the modification.

Glass-Filled Wood-Polymer Composites Based on Polypropylene

Abstract: This paper describes the study on the influence of glass spheres on physicochemical and service properties of wood-polymer composites (WPC) based on polypropylene. The main objective of doping WPC with glass spheres was to reduce density of composites maintaining their service properties.
