Summary: BTD, a new bioadditive for PVC, exhibits higher plasticizing efficiency, thermal stability, and UV absorption properties compared to traditional plasticizers like dioctyl phthalate. Its thiazolopyridine structure gives BTD excellent UV shielding capability, making it a promising additive for PVC plasticization and anti-UV applications.

Summary: In this study, a method to improve the dispersion of graphene in rigid poly(vinyl chloride) matrix using a plant extract from Curcuma longa L. is proposed. The use of the proposed extract as a dispersant resulted in improved dispersion, mechanical properties, thermal stability, and glass transition temperature of the nanocomposites. This suggests that the extract can be a promising eco-friendly additive for the production of nanocomposites with enhanced homogeneity.

Summary: In this study, a modified silk fibroin (SF-BGE) soluble in water was prepared by introducing butyl glycidyl ether (BGE) into its side chain. A coordination bond between ZnO and tannic acid (TA) was formed to develop an SF-based nanocomposite hydrogel. The hydrogel showed superior hemostatic and cytocompatible activities.

Summary: This study designs a ternary nanomaterial structure containing a quaternary chalcogenide nanocomposite to address the deficiencies in poor semiconductor materials for CO2 reduction. The ternary photocatalyst, AgFeNi2S4-Graphene-ZnO, shows high levels of CO2 reduction to methanol due to the improved charge transfer between the components. The stability and recyclability of the photocatalysts were also determined.

Summary: The study evaluated the preparation and properties of starch/polyvinyl alcohol/ZnO nanoparticles films using response surface methodology, revealing that hydrogen bonding interactions between PVA and starch improved film formation. The effects of glycerol and PVA content on mechanical strength were contradictory, with PVA content initially decreasing and then increasing tensile strength.

Summary: The separation of gold from wastewater using polymer-based adsorbents is an efficient method to recycle precious metal resources. A novel poly(vinyl chloride) nanofiber functionalized with phos-phonic acid (PVC-APA) showed excellent adsorption performance for gold, with a maximum adsorption capacity of 336.36 mg/g. The adsorption behavior followed a pseudo-second-order kinetic model and Langmuir adsorption isotherm, indicating a spontaneous and endothermic process. The ability of PVC-APA to adsorb gold remained strong even in the presence of interfering ions, and it exhibited satisfactory reusability. The study also revealed the chelating ability of PVC-APA with gold, where the gold ions could be partially reduced to gold metal through a redox reaction with the amino groups.

Summary: This study developed a greener method for fabricating large-scale nanofiltration (NF) membranes using polydopamine (PDA) and polyethyleneimine (PEI) co-deposition. The addition of metal-organic framework (MOF) UIO-66 improved the properties of the NF selective layer and enhanced the surface area, resulting in higher permeability. The ternary coated NF membrane exhibited good performance with low molecular weight cut-off, high permeance, and high rejection rates for MgCl2. This research contributes to the advancement of sustainable NF membrane fabrication.
