Summary: The study found that decayed wood plastic composites with chitosan exhibited better properties than decayed wood plastic composites without any additive, and even better than sound wood plastic composites. Adding chitosan to decayed wood powder and PVC improved the performance of the DWPC, reaching the level of sound wood plastic composites. This work proposed a novel green strategy for utilizing decayed wood for making polyvinyl chloride/wood flour composites.

Summary: The study investigated the use of three zinc salts in WF-PVC composites, finding that zinc borate and zinc stannate had some negative effects on thermal stability, but promoted char formation. Zinc exhibited stronger charring ability compared to tin. Zinc stannate and zinc borate were effective flame retardants, delaying ignition time and reducing heat and smoke release.

Summary: The study demonstrated that chemically treated wood flour is more effective in improving the mechanical and physical properties of polyvinyl chloride compared to untreated wood flour. This suggests that chemically treated wood flour could be a promising substitute for chalk as a filler in PVC-based applications.

Summary: Core-shell composites with strong weather resistance, mechanical strength and creep resistance can be prepared using co-extrusion technology. The trapezoidal mortise and tenon structure had the best interface bonding, bending properties and creep resistance among the three types tested, which effectively improved the dimensional stability of the co-extruded composite after water absorption.

Summary: This paper investigates the preparation of environmentally friendly wood-plastic composites (WPCs) using corn stalk as the raw material. By optimizing the pretreatment method and selectively removing lignin and hemicellulose, the mechanical performance of the WPCs is improved. The sample with both lignin and hemicellulose removed shows the highest crystallinity and fibrous morphology, and exhibits significantly increased tensile strength, modulus, flexural strength, and modulus compared to regular WPCs. Additionally, the extracted lignin and hemicellulose can be further utilized for valuable biochemical products, adding value to both WPC materials and biorefinery products.

Summary: In this study, wood veneer/wood flour-polyvinyl chloride composites (WWPVCs) were treated with a silane coupling agent to improve their interfacial bonding, mechanical properties, and resistance to moisture and heat. The treated samples showed superior performance compared to those treated with other interface modifiers. Silane coupling agents are easily prepared and environmentally friendly.

Summary: In this study, a flame retardant system was developed for wood plastic composite (WPC) by combining ammonium polyphosphate (APP) with lignin (L). The optimal ratio of L/APP was determined and the distribution of the flame retardant system in the WPC was analyzed. The concentrated distribution of the flame retardant system in the surface layer of the WPC showed improved flame retardant performance and maintained better mechanical properties.

Summary: The study investigated the effect of plant species on the accelerated weathering behaviors of polyvinyl chloride-based wood-plastic composites (WPCs), revealing changes in color, chemical composition, water absorption, and swelling ratio of the weathered WPCs. Eucalyptus-based composite exhibited the highest mechanical properties among the tested plant species.

Summary: This paper investigated the effect of OMMT modification on wood flour/poly (lactic acid) composites, revealing that nearly all mechanical properties showed improvements after modification, except for impact strength. Composite made of pure PLA and OMMT-modified WF exhibited the best mechanical properties, while composite made of pure WF and OMMT-modified PLA showed the worst performance.

Summary: This study investigates the properties of WPCs made from wood flour and wood pellets, showing that composite products from wood pellets have higher density but lower tensile strength, tensile modulus, and impact strength compared to those made from wood flour. Flexural properties of composites made with pellets were higher without MAPP, but lower with it. Overall, the mechanical property differences between the two were low (0.5-10%) depending on the specific WPC formulations. Statistical analysis indicated no significant differences in material properties between composites made from wood flour and wood pellets, with some situations showing better WPC properties using wood pellets.

Summary: The risk of retained surgical items is a serious medical danger and liability issue. Radiofrequency scanning technology is an effective method to reduce these accidents. This study proves that bismuth oxychloride (BiOCl) is a suitable alternative to barium sulfate (BaSO4) as a radiopaque agent, offering excellent stability and dispersibility within the PVC matrix. Using half the amount of BiOCl compared to BaSO4 provides satisfactory results, as demonstrated through various analytical methods.

Summary: In this study, graphene oxide (GO) was incorporated into the polyvinyl chloride (PVC) matrix to improve the migration resistance of phthalic plasticizer. The sheet structure of GO, coupled with its abundant oxygen-containing groups, allowed for better blending with PVC and prevented the plasticizer from migrating.

Summary: Polyvinyl chloride (PVC)-containing waste streams are difficult to recycle due to the high chlorine content. A novel recycling approach was developed to leverage PVC as an asset. Co-conversion of red oak and PVC in a green solvent resulted in the production of valuable compounds and chlorine-free solid fuels.

Summary: By studying the rheological properties of UF-WFPE under continuous deformation, a modified plug flow model was proposed to explain the rheological behavior of UF-WFPE melt. The study found that specimens with 70 wt%, 75 wt%, and 80 wt% WF displayed a stable rheological behavior period during compression, while those with 90 wt% WF entered a continuous fracture stage, lacking a stable rheological behavior period.

Summary: Food serving containers made from cellulose nanofibers exhibit excellent oil and grease resistance, mechanical properties, and environmental friendliness as they are derived from wood flour. These containers can serve as a sustainable alternative to commercial food containers without the use of poly-fluoroalkyl substances.
