This study addresses these challenges by investigating the incorporation of nanochitin and nanocellulose fillers into PBS/PBAT blends, aiming to optimize their mechanical properties and to control the degradation behavior for marine environments. First, various PBS/PBAT nanocomposites were prepared with chitin and cellulose nanofillers, and tensile tests identified the most effective fillers for mechanical reinforcement.

However, the actual application environment is complex and changeable, and the failure of the material is a common problem in the use process. Fluorinated polyurethane acrylate was synthesized via the fluorinated unit alcohol end-capping approach to enhance the antioxidant capacity of gas separation membranes. The fluorine element is used as an important part of the membrane structure, and then the antioxidant capacity of the membrane is enhanced. Specifically, hexamethylene diisocyanate isocyanurate (HDI) trimer and 1H, 1H, 2H, 2H-Tridecafluorooctanol (TFOA) were precisely metered and underwent an addition reaction. Subsequently, two molecules of the resulting addition products were connected to a molecule of 1,6-hexanediol (HDO). This was followed by a nucleophilic addition reaction between hydroxyethyl methacrylate and the fluorine-rich molecular formula, yielding fluorinated polyurethane acrylate (FPUA). To fabricate the gas separation membrane, photoinitiators were incorporated into the FPUA, followed by curing under UV irradiation. Under optimized conditions, the membrane exhibited exceptional performance in CO₂/SF₆ separation, achieving a gas selectivity of 126.11. The presence of abundant carbon, fluorine, and oxygen atoms in the separation layer significantly bolstered its antioxidant properties. After immersion in a 1 g/L NaClO solution for 7 days, the membrane exhibited minimal corrosion loss of only 1.5% ± 1.3%, and the water contact angle decreased by just 1.8°.

The waste metallized plastic fillers were found to have no interactions with the foam chemically, as confirmed by Fourier transform infrared spectroscopy results. Thermal conductivity and compressive strength of the foam samples were found to increase with the increase in filler loading.

This extended model considers the free energy of swelling hydrogels to include network deformation energy, mixing energy, and ion energy, with the effects of ion concentration and reaction on free swelling being an ionic mechanochemical coupling effect. The Flory-Huggins dilute solution theory, scaling theory, reaction kinetics, and Clausius-Mosotti equation are employed to estimate the Flory-Huggins interaction parameters and thermodynamics of hydrogels.
