Summary: This study aimed to improve the properties of PLA films by incorporating potato and rice starch nanocrystals (SNCs) into the PLA matrix. The addition of 1 wt% potato SNCs increased tensile strength, elongation, and glass transition temperature while reducing water vapor permeability. These findings suggest that potato SNCs can serve as a structural reinforcement for PLA films, making them suitable for various applications.

Summary: In this study, multi-scale hexagonal boron nitride (hBN) and titanium dioxide (TiO2) fillers were integrated into polyetheretherketone (PEEK) polymer to create a thermally conductive composite material. As a result, the 50B-10T composite exhibited an ultrahigh thermal conductivity of 8.195 W/(m.K), with a 3139% enhancement compared to unfilled PEEK. Moreover, efficient channels for phonon transport were formed between hybrid fillers, and the through-plane thermal conductivity reached 1.704 W/(m.K) in the 50B-10T sample.

Summary: In this study, rPE based MFCs were developed by incorporating rPET and rPA as reinforcing fibrillar phases at a given weight ratio. The effects of extrusion and injection molding temperatures on fibrillar structure and properties were explored. EnBAGMA and MAH-g-PE acted as compatibilizers, refining the fibrillar structure and significantly influencing mechanical properties.

Summary: This study aimed to create an oral swab for capturing and concentrating Mycobacterium tuberculosis (Mtb) using a modified polymer material. The polymer, surface functionalized with Concanavalin A, was found to effectively capture Mtb cells in dilution studies. The results suggest that the modified fibers could potentially aid in rapid detection of TB in paucibacillary cases.

Summary: Extrusion blow molding technology is commonly used for manufacturing plastic bottles, but less so for bottles made from environmentally friendly bioplastics. This study focused on designing PLA/PBS/micro-lamellar talc compounds for bioplastic bottles, particularly for wine packaging. The experimental results showed that these bio-derived polyester resin blends can be effectively processed through extrusion blow molding, offering potential as a low environmental impact alternative to oil-based plastics in wine bottle production.

Summary: In this study, a transparent composite is developed by matching the refractive indices of E-glass fiber and a polymer blend. The composite features highly miscible polycarbonate and polycaprolactone as the matrix to avoid opacity caused by phase separation. The optimal transparency is achieved at a PC:PCL weight ratio of 65:35, and the composite exhibits superior mechanical strengths compared to PC and short glass fiber-reinforced composites.

Summary: This study successfully prepared PVA/carbon fiber (CF) composite film with excellent performance by using PVA as matrix and performing melt casting and asynchronous biaxial stretching. The addition of CF improved the electrical properties of the composite precursor sheet, and the subsequent biaxial stretching enhanced the arrangement of CF and orientation of PVA molecular chains, resulting in the composite film with outstanding mechanical strength, antistatic properties, and water resistance.
