“…The main approaches refer to (1) the surface modification techniques applied to wood—chemical and biochemical (enzyme), physical, radiative, and mixed methods [ 34 ]. (2) The use of compatibilizers incorporated into the polymer matrix—such as malleated polyolefins, which are highly recommended for the respective polyolefin matrices [ 22 ]; ethylene diamine tetraacetic acid (EDTA), a reactive compatibilizer for poly(lactic acid)/poly(butylene adipate-co-terephthalate) mixed matrix [ 35 ]; ionic liquids [ 36 ]; glycidyl methacrylate and polyethylene-co-glycidyl methacrylate [ 37 ]; and mixtures of malleated polyolefins [ 38 ]. And lastly, (3) any combination of methods wisely chosen and applied simultaneously to both matrix and reinforcement.…”

Wood–polymer composites (WPCs) are a class of materials intensively studied and promoted in the context of sustainable development, mainly when aspects related to the increasing awareness of environmental issues and waste management are considered. Feasible opportunities for producing WPCs with value-added properties intended for common applications emerge when polymers, either synthetic or from renewable resources, raw or waste, are employed in re-/up-cycling approaches. In this context, some examples of easily achievable WPCs are presented herein, namely, formulations based on different wood waste and polymer matrices (synthetic: polypropylene and malleated polypropylene as a compatibilizer; natural: plasticized starch). Their level of performance was assessed through different characterization methods (FTIR, WAXD, TGA, DSC, mechanical test, etc.). The benefits and limitations of this approach are also discussed.

Polylactic acid (PLA) is regarded as the most representative biomedical polymer materials. However, some problems, that is, its big brittleness, high hydrophobicity, and poor bioactivity, limit its application. Here, using poly(butylene adipate‐co‐terephthalate) (PBAT) as toughening agent, and incorporating ethylene diamine tetra(methylene phosphonic acid) (EDTMPA) for the first time with nano‐hydroxyapatite (nHA) as reinforcement filler, series of PLA/PBAT/nHA/EDTMPA as novel bone scaffold composites are successfully prepared via simple one‐step melt extrusion. The chemical composition, microstructures, thermodynamic properties, mechanical properties, hydrophilicity, and bioactivities of PLA/PBAT/nHA/EDTMPA were characterized. The test results show that these developed PLA‐based composites from safe biosources are greatly potential raw materials for bone scaffold because the existence of EDTMPA can chelate with calcium ions to promote calcium phosphate (CaP) deposition on the surface of bone scaffold composites. Especially, when the content of EDTMPA is 6 wt%, the comprehensive performance of the bone scaffold composite is the best. The research results indicate that these developed PLA‐based materials are greatly potential raw materials for bone scaffold composites.

In this study, a novel biodegradable coir fiber (CF) reinforced thermoplastic starch (TPS) and poly(butylene adipate‐co‐terephthalate) (PBAT) composites (CF/TPS/PBAT) with a constant TPS: PBAT weight ratio of 70:30 and 5, 10, 15, and 20 wt% additions of CF were prepared by the melt blending and injection molding. The effects of fiber content and fiber surface modification on the mechanical and thermal properties of the prepared biocomposites were investigated. The incorporation of fibers effectively enhanced the mechanical and thermal properties of TPS/PBAT blends. Due to the removal of hemicellulose and impurities on the fiber surface after alkali treatment, the interfacial adhesion of the fiber was enhanced, thus improving the compatibility between the fibers and the matrix. At 20 wt% CFs with alkali treatment, the tensile strength exhibited 393% improvement and flexural strength exhibited 536% improvement over TPS/PBAT blends. Thermal analysis showed that the thermal stability, storage modulus, and glass transition temperature of the composites increased with the increase of fiber content. This work is significant for the development of biodegradable materials.
