Natural fibres are highly desirable in composites as they are renewable, biodegradable, and cost-effective. They are also abundant in nature with many different types available all over the world. However, despite their advantages, key challenges such as poor fibre-matrix interfacial bonding and moisture absorption limit their widespread adoption in more sophisticated applications. This article provides an overview of natural fibres, including classifications, types, properties, advantages, and disadvantages, with a subsequent review of recent studies, focusing on fibre-matrix selection, treatment methods, and characterization to better understand the current situation. It is apparent from these studies that water absorption is a significant challenge due to the inherent hydrophilic nature of natural fibres as even after treatments like mercerization and silane were applied, substantial amounts of absorption were observed. The effects of powder fillers also vary, with beneficial effects up to a certain proportion, beyond which they became detrimental.

The treatment of waste plastics has gradually become a hot topic in the current scientific community. In response to the needs for high-impact performance R-PP-based composites, carbon fiber (CF)-reinforced polyolefin elastomer (POE)/recycled polypropylene (R-PP) composite (CF/POE/R-PP) was prepared by the mechanical blending method, and its mechanical and thermal properties were systematically studied. It was found that the CF could effectively improve the bending and notch impact strength as well as enhance the thermal stability of POE/R-PP. Furthermore, a stable and dispersed composite interface formed by the combination of maleic anhydride-grafted polypropylene (PP-g-MAH) with the surface of CF and the fusion alkyl chains in R-PP and POE further enhanced the CF’s reinforcing effect. As a result, the addition of 9 wt.% CF successfully improved the heat resistance of the composite material, and the residual carbon content increased by 97.84% after sintering. The composite toughening of POE and CF effectively improved the impact strength of the composite material, with a maximum increase of over 1000%. This study ultimately resulted in a high-impact-resistant composite material.

“…Since Natta succeeded in polymerizing propylene into polypropylene (PP) using aluminum chloride and titanium chloride as catalysts, 1 and establishing the theory of directional polymerization and industrializing PP, the application areas of PP has been expanded and its quantity demanded continues to grow year by year. [2][3][4][5] However, the wide forbidden band and low hygroscopicity of PP, make it easier to generate static electricity and lead to malfunctioning of electronic devices, fire or explosion. 6,7 Therefore, the adoption of proper antistatic methods to prevent the creation of static electricity in PP will considerably extend the market for its usage.…”

In this paper, a novel polymeric antistatic agent, TMQ, with excellent antistatic properties, low cost, and good compatibility with polypropylene (PP), was prepared from isopentenyl polyoxyethylene ether (TPEG), maleic anhydride (MAH) and homemade quaternary ammonium salt (QAS). The structure is characterized using FTIR and 1H NMR. How the addition of TMQ and the molar ratio of TPEG, QAS, and MAH affect the antistatic, mechanical, and crystalline properties of PP are investigated. The results show that as the feed ratio of TPEG, MAH and QAS is TPEG:MAH:QAS = 1:8:8, the modified PP displays the best overall performances. Further exploring finds out when TMQ is added at 15 wt%, the surface resistivity of PP reduces to 6.78 × 109 Ω/sq and the volume resistivity of PP reduces to 7.9 × 109 Ω cm−1, the notched impact strength and melt index improve by 357% and 991%, respectively, while the tensile strength decreases by 38.6% compared with that of pure PP. Besides, the crystal study shows after TMQ is added, the crystallinity of PP reduces, the melt peak temperature remains essentially unchanged, and the crystallization peak temperature increases slightly. The material has excellent antistatic resistance to washing and durability, and the changes in relative humidity have little effect on its antistatic properties.
