High performance and durability are essential for goods to satisfy the needs of the expanding worldwide market. Wood plastic composites (WPCs) are materials made from a combination of wood, polymers, and additives. WPCs can be extruded, injected, compressed, or thermoformed. Presently, WPCs are manufactured using sophisticated processes including as laser sintering, fused layer modeling, and additive manufacturing. Properly managing the melt temperature and pressure is crucial in the manufacturing process of WPCs to ensure effective polymer incorporation. Natural fibers have distinct benefits for polymer composites, but they also have some serious drawbacks, like lower strength properties—especially lower impact strength than synthetic fibers—poor compatibility with hydrophobic polymers, poorer dimensional stability and moisture absorption due to hydroxly groups, a maximum processing temperature that is limited, thermal degradation above 200–220°C, and lower biological durability. The modification of the surface of the fibers improves the mentioned disadvantages of the natural fibers. High‐quality WPCs require the application of chemical or physical treatment to the wood fibers. This extensive review focused on the modification techniques applied to the surface of wood, manufacturing processes, and properties and applications of WPCs.Highlights Modification methods used in surface treatment of natural fibers was explained. Properties and recent applications of wood polymer composites were given. Optimum requirements of natural fibers and polymer matrices are given. Fabrication methods of natural fiber composites are extensively given.

“…A number of research groups have already studied how the WPCs properties have been affected by the addition of different coupling agents [10,11]. Nanoparticles' influence on WPCs properties has also already been the focus of some research [12,13] as well as for other types of resins and composites [14].…”

The influence of nanolignin coupling bio-agent on some characteristics of polypropylene-wood flour composites was studied. Thus, nanolignin was prepared by the acidic method, and then different ratios of it (0, 1, 3 and 5 wt%) were added to a polypropylene-wood flour mixture. After mechanically mixing wood flour, nanolignin, and polypropylene, the mixture was injection molded. ASTM methods were used to measure the structural properties of nanolignin, and prepared composites' water absorption, thickness swelling, bending modulus, and bending, tensile and impact strengths. Transforming the original lignin to nanolignin did not change the chemical bonds of the material. The addition of nanolignin yielded improved mechanical and physical properties of the composites prepared. Higher strength and dimensional stability are presented by nanolignin-containing composites when comparing them with those prepared with normal lignin. Nanolignin was shown by SEM (Scanning Electron Microscope) observation to be uniformly dispersed within the polymer matrix. Wood polymer composites (WPCs) with nanolignin exhibited comparable properties with the control samples prepared using maleic anhydride polypropylene (MAPP).

“…Coupling agents are easier to handle than alternative methods used to improve the interfacial bonding between wood and thermoplastics. Coupling agents chemically interact with natural fibers and mechanically with the hydrophobic matrices enhancing the compatibility and consequently achieving a better interfacial bonding [2][3][4][5][6].…”

Agave tequilana Weber var. azul fibers (ATF) are widely used as a reinforcement material despite their polarity makes them incompatible with hydrophobic matrices. Consequently, ATF are commonly modified employing different chemical processes (e.g., mercerization and coupling agents) to change their surface characteristics to improve the interface between the fibers and the polymeric matrix. Nevertheless, these treatments could damage the fibers during the process, negatively affecting their natural properties. The use of nanotechnology to repair this natural material could help to restore its intrinsic properties and give it new ones as antibacterial activity. In this work, chemically treated ATF were used as templates for the biosynthesis of silver nanoparticles (AgNPs) using a natural extract obtained from Agave tequilana Weber var. azul leaves (ATL) as reducing agent. Scanning and transmission electron microscopy images as well as dynamic light scattering results indicate that stable nanometric particles were successfully synthesized on all fibers. X-ray photoelectron spectroscopy and X-ray diffraction results confirm the composition of the nanoparticles. Tensile tests indicate that AgNPs improved the mechanical properties of fibers previously mercerized and treated with maleic anhydride grafted polyethylene as coupling agent. Additionally, an antibacterial effect against S. enterica was conferred to ATF due to the presence of AgNPs.
