“…It is assumed that the vegetable oils fill vessels and valves and thickens the walls, cross-links, forms a denser film, and owes to better lateral stability to the hemp shives, which normally fail in compression due to buckling of thin valves and vessels walls. Similar findings were reported by other researchers who investigated the dimensional stability and mechanical behavior of the oil-impregnated wood and particleboards [ 28 , 36 ]. Increasing the hardening temperature up to 120 °C shows the negligible change in strength value for F composition, while it becomes similar to those at 40 °C oil-hardening temperature for G and H composition.…”

“…This behavior can be a result of tung tree oil hydrophobicity and structure, which forms a thick layer on the external surface as well as porous aggregate structure. Similar conclusions were made previously for rice husk and soy protein-based particle boards impregnated with tung tree oil [28,29]. However, H-type BcB has increased water absorption, which, compared to the results obtained for F-type and G-type BcBs, suggests that F-or G-additives together with the tung tree oil form some kind of synergy, i.e., F-additive forms a thin protective layer on hemp shive surface, whereas G-additive interferes with corn starch binder.…”

In this study, tung tree and linseed drying oils, as well as semi-drying hempseed oil, were analyzed as the protective coatings for biocomposite boards (BcB) made of hemp shives, corn starch binder, and the performance-enhancing additives. The hydrophobization coatings were formed at 40, 90, and 120 °C temperatures, respectively. The physical-mechanical properties such as the compressive strength, thermal conductivity, dimensional stability, water absorption, and swelling were tested. In addition, scanning electron microscopy (SEM) was employed for the analysis of the board microstructure to visualize the oil fills and impregnation in pores and voids. It was demonstrated that the compressive strength of oil-modified BcBs compared to uncoated BcBs (at 10% of relative deformation) increased by up to 4.5-fold and could reach up to 14 MPa, water absorption decreased up to 4-fold (from 1.34 to 0.37 kg/m2), swelling decreased up to 48% (from 8.20% to 4.26%), whereas the thermal conductivity remained unchanged with the thermal conductivity coefficient of around 0.085 W/m·K. Significant performance-enhancing properties were obtained due to the formation of a protective oil film when the tung tree oil was used.

“…Researchers have also used hydrophobic materials to increase the water resistance of the composite structure. As an example, Chalapud et al [ 61 ] used a tung oil in RH that was adhesively bonded by a soy protein composite to improve the moisture resistance of particleboard. The impregnation of the composite panel with tung oil decreased its moisture absorption capacity and reduced the volume of voids, as obtained by surface microscopy.…”

Recent Progress of Rice Husk Reinforced Polymer Composites: A Review

et al. 2021

View full text Add to dashboard Cite

Recently, because of the rising population, carbon overloading, and environmental distress, human beings have needed to increase awareness and responsibility for the reduction of agricultural waste. The utilization of agricultural waste as a filler material in reinforced polymers is a fascinating discovery. This review paper attempts to study the physical, mechanical, and thermal behavior of rice husk (RH) as a fiber for reinforcing various synthetic polymers, based on recent studies, conducted between 2017 and 2021. It also highlights that advanced modification techniques could further improve the performance of composites by tailoring the physical and chemical substances of the fiber or matrix. The thermal properties, including flame-retardance and thermal behavior, are also discussed. The characteristics of the fiber–matrix interaction between RH and the polymer matrix provide essential insights into the future-ready applications of this agricultural waste fiber. The way forward in researching RH polymer composites is finally reviewed.

“…[127] Finally, new technological and advanced materials can be produced using SBP, as it is a good adhesive in particleboards for construction materials and can substitute toxic and petroleum-derived adhesives. [128] Gels formed by SBP/xanthan gum with sodium chloride were shown to be promising materials for 3D printers, [129] and a transparent-flexible supercapacitor can be developed using SBP and hydroxyethyl cellulose as the polymeric matrix and lithium sulfate as the electrolyte.

This Review highlights the principal crops of Brazil and how their harvest waste can be used in the chemicals and materials industries. The Review covers various plants; with grains, fruits, trees and nuts all being discussed. Native and adopted plants are included and studies on using these plants as a source of chemicals and materials for industrial applications, polymer synthesis, medicinal use and in chemical research are discussed. The main aim of the Review is to highlight the principal Brazilian agricultural resources; such as sugarcane, oranges and soybean, as well as secondary resources, such as andiroba brazil nut, buriti and others, which should be explored further for scientific and technological applications. Furthermore, vegetable oils, carbohydrates (starch, cellulose, hemicellulose, lignocellulose and pectin), flavones and essential oils are described as well as their potential applications.
