Summary: This study investigated the production of LLDPE/OP films using blown film extrusion and evaluated the effect of OP content on film morphology and properties. The results showed that blown LLDPE/OP films containing up to 11.5% OP could be produced, with similar water barrier, crystallinity, and melting temperature to neat LLDPE films, but lower tensile strength and elongation at break. The addition of OP also enhanced the UV and visible light blocking capacity of the films.

Summary: In this study, biocomposite films containing EPS from probiotic Enterococcus faecium MC-5 were successfully prepared using the plate casting method and combined with PVA and chitosan. The EPS was evenly distributed in the films, improving their physicochemical properties. The intermolecular connections between the polymers were detected, resulting in high tensile strength and low water vapor transmission rate. The EPS-based films showed a greater antioxidant property, metal chelation activity, and antibacterial properties compared to chitosan and PVA films. They also had a higher degradation rate, suggesting their potential as sustainable packaging materials.

Summary: Inspired by nature, humidity-responsive materials and devices have attracted significant interest from scientists in multiple disciplines, ranging from chemistry, physics and materials science to biomimetics. Owing to their superiorities, including harmless stimulus and untethered control, humidity-driven materials have been widely investigated for application in soft robots, smart sensors and detectors, biomimetic devices and anticounterfeiting labels. Especially, humidity-responsive liquid crystalline materials are particularly appealing due to the combination of programmable and adaptive liquid crystal matrix and humidity-controllability, enabling the fabrication of advanced self-adaptive robots and visualized sensors.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
