AI Article Synopsis
- The study investigates waterborne polyurethane acrylate (WPUA) films combined with varying amounts of MXene (TiCT) using UV-curing technology, aiming to enhance their properties.
- Incorporating MXene improves the films' hydrophilic characteristics and optimizes mechanical properties, with the best performance seen at 0.077 wt% MXene load—resulting in significant increases in tensile strength and elongation at break.
- Additionally, the presence of MXene enhances the thermal stability and glass transition temperature of the composites, showcasing its potential in UV-curable coatings.
Article Abstract
In this study, waterborne polyurethane acrylate (WPUA)/MXene nanocomposite films with varying MXene loadings were fabricated using UV-curing technology, where MXene (TiCT) was employed as a nanofiller. The microstructure and chemical structure of the WPUA/MXene nanocomposite films were examined by XRD and FTIR, respectively. The water contact angle testing demonstrated that the incorporation of MXene into the nanocomposite films led to an increase in their hydrophilic properties. The tensile strength, the elongation at break, and Young's modulus of the WPUA/MXene nanocomposite coatings exhibited an initial increase followed by a decrease with increasing MXene loadings. Compared to the pure WPUA film, the tensile strength and elongation at break of nanocomposites with 0.077 wt% MXene loading reached their maximum values, which increased by 39.9% and 38.5%, respectively. Furthermore, the glass transition temperature and the thermal stability were both enhanced by MXene to some extent. This study introduces a novel method for utilizing MXene in UV-curable waterborne coatings.

Smart packaging, also known as intelligent packaging, is responsive to external stimuli, moisture, light, oxygen, heat, pH, and bacterial growth. In this study, polyvinyl alcohol/nanochitosan/phycocyanin nanocomposite (PVA/NCH/PC-NC) for fish fillets of Oncorhynchus mykiss rainbow trout coating was prepared. Five treatments were prepared over a period of 14 days (0, 1, 7 and 14 days) under treatments of T: fish coated with PVA/NCH-NC without PC; T, T T and T fish coated with PVA/NCH/PC-NC (0.

Article Synopsis
- The study focuses on creating composite films of poly (methylmethacrylate) (PMMA) blended with magnesium oxide quantum dots (MgO QDs) at varying concentrations, and the films were annealed at 130°C for different durations to observe changes in their properties.
- Analysis revealed that the initial crystallinity of the PMMA films decreased with annealing but slightly improved with the diffusion and coalescence of MgO QDs, leading to the formation of larger clusters that influenced the films' structural properties.
- The research highlights the significance of temperature and molecular forces in the evolution of the film's morphology and stability, demonstrating unique energy dissipation mechanisms and the complex interplay of inter- and intra

Article Synopsis
- The study examines how poly(lactic acid) (PLA) nanocomposite films with Hec-g@PS perform in extreme natural environments, focusing on their degradation and ability to adsorb Cu(II).
- During degradation, PLA/Hec-g@PS films exhibited lower roughness and crack rates compared to standard PLA films, likely due to enhanced interactions within the material that slowed degradation.
- The PLA/Hec-g@PS films not only extended lifespan by 1.08 times but also showed improved Cu(II) adsorption, making them promising for applications in wastewater treatment and soil remediation.

Chitosan (CH)-based composite films have attracted increasing attention as promising green food packaging materials due to their biodegradability and ease of fabrication. Additionally, lignin (LN) has been widely used as additive for chitosan-based films to improve their physicochemical properties. In this study, a series of composite films made of chitosan nanoparticles (NCH) as a matrix and alkali lignin nanoparticles (LNPs) as functional filler were prepared.

This study aims to explore the redispersibility of dehydrated nanocellulose with p-toluenesulfonic acid (p-TsOH) fractionated lignin as an eco-friendly and cost-effective capping agent, to cope with the challenge of irreversible agglomeration and thus loss of nanoscale of nanocellulose upon dehydration. The intermixing of nanocellulose and p-TsOH fractionated lignin was achieved using an aqueous ethanol solution as the medium and films of lignin-blending cellulose nanofibers (L + CNF) with excellent redispersing properties were obtained after facile air-drying.
