Summary: In this paper, large-size reeds were added into PBAT to prepare high-performance biodegradable composites without using a compatibilizer. The effects of these large-size reeds on the properties and biodegradation behavior of the composites were investigated. The results showed that the composites exhibited improved modulus, flexural strength, and heat deflection temperature compared to pure PBAT. Biodegradation tests also revealed significant differences between the composites and PBAT in terms of mass loss, thermal stability, melting point, and crystallinity during degradation. A surface erosion degradation model for the composites was proposed, providing a scientific basis for their application in biodegradable blister and injection molded products.

Summary: More than 390 million tons of fossil fuel plastics have been produced in 2022, causing major health issues and environmental pollution. Bioplastics are considered as a promising alternative due to their carbon neutrality and biodegradability, but technical and cost limitations prevent them from fully substituting fossil fuel plastics.

Summary: Food packaging material is crucial for sustaining food quality and safety in the food industry. Traditional food-grade materials negatively impact the safety, shelf life, texture, quality, and flavor of food commodities. Biotechnology offers techniques to produce edible packaging materials, such as polysaccharides and protein-based films, intelligent and active packaging, which can preserve food and prevent the entry of harmful components. Various materials are used to produce edible packaging with active and intelligent characteristics, making it safer and more nutritious for consumption. However, there is a need to develop edible packaging for liquid commodities, like dairy and beverages, using biotechnological techniques.

Summary: Poly(butylene adipate-co-terephthalate) (PBAT) was improved in terms of oxygen and water vapor barrier properties by incorporating poly(ethylene-co-vinyl alcohol) (EVOH). The addition of 50 wt% EVOH resulted in a 77% reduction in OTR and a 40% reduction in WVTR. The compatibility between PBAT and EVOH limited the elongation at break of the blends, with a decrease observed after 20 wt% EVOH. FTIR analysis confirmed limited hydrogen bonding between PBAT and EVOH. EVOH accelerated the hydrolytic degradation of PBAT but had no effect on biodegradation in soil.

Summary: The precipitation method was used to synthesize a poly(epsilon-caprolactone-copolymer-ethylene oxide) composite with lanthanum salt. The thermal and dielectric properties of the polymer were studied by incorporating different weight percentages of the salt. Characterization techniques such as Fourier Transform Infrared Spectroscopy, X-ray diffractometry, scanning electron microscopy, and thermogravimetric analysis were used. The results showed that the thermal stability of the composites was lower than that of the pure polymer, and the dielectric properties and AC conductivity increased with increasing lanthanum content. This eco-friendly and easy-to-handle method provides a promising route for polymer composites in the field of conductivity.

Summary: This study found that PBAT emits bright blue-green fluorescence under UV irradiation and developed a degradation evaluation approach based on fluorescence tracking. The fluorescence wavelength of PBAT shifted blue as the film thickness and molecular weight decreased during degradation. The fluorescence intensity of the degradation solution increased gradually with degradation and exhibited an exponential correlation with the concentration of benzene ring-containing degradation products.

Summary: This study investigates the reinforcement effect of three herbaceous biomass fillers on PLA composites. The results show that PLA composites reinforced with reed exhibit optimal mechanical properties, with over 7000 MPa flexural moduli when filled with 40%-50% reed. Furthermore, the introduction of biomass fillers increases the crystallization ability of PLA without increasing water absorption.

Summary: The high aspect ratio jute fibers in PLA composites create a strong crisscross structure, resulting in improved mechanical properties. Additionally, the addition of jute fibers enhances the thermal resistance and crystallization ability of the PLA composites. Utilizing biomass filler with high content and large aspect ratio proves advantageous in modifying PLA materials.

Summary: Two fibrous fillers obtained from Chamaerops humilis dwarf palm were tested as reinforcing agents for PBAT-based composites. The results showed that these fillers can effectively overcome the limitations of PBAT, improving the stiffness and cost-effectiveness of the composites while maintaining their stretchability and environmental sustainability. The formation of a robust interphasic region, attributed to the chemical affinity between the fillers and the matrix, played a crucial role in the mechanical performance of the resulting biocomposites.

Summary: The study investigated the application of novel compatibilizers and plasticizers derived from epoxidized chia seed oil and maleinized chia seed oil in composites based on poly(lactic acid) and chia seed flour. The addition of these compatibilizers improved the mechanical and thermal properties of the composites and enhanced the interfacial adhesion between the chia seed flour particles and the poly(lactic acid) matrix.

Summary: Reed has the potential to be a promising biorenewable energy source, as it can grow rapidly even in challenging environmental conditions. Ball-milling pretreatment and enzymatic hydrolysis can significantly reduce the hemicellulose and lignin content in reed, leading to the extraction of a residue with excellent mechanical properties for bio-based composites.

Summary: The usability of LD slags as reinforcement material in epoxy composites was investigated. The physical, mechanical, and tribological properties of the composites were studied. The experimental results showed that the density, void content, and water intake capacity of the composites increased with LD slag loading. The tensile and flexural strength were slightly compromised, but the compressive strength increased with filler content. A forecast model based on an artificial neural network successfully predicted the sliding wear performance of the composites.

Summary: Biodegradable polymers have attracted significant attention due to their environmentally friendly compostability. However, challenges remain for their practical application in packaging, particularly in addressing gas/moisture barrier issues. Various strategies have been researched for decades to overcome these challenges, such as chain architecture tailoring, crystallinity, melt blending/multi-layer co-extrusion, nanotechnology, and surface coating. This review focuses on improving the oxygen/water vapor barrier properties of biodegradable polymers and discusses the limitations of current methods and potential solutions.
