Recent Advances in Poly(vinyl alcohol)-Based Hydrogels

Polymers, Journal Year: 2024, Volume and Issue: 16(14), P. 2021 - 2021

Published: July 15, 2024

Poly(vinyl alcohol) (PVA) is a versatile synthetic polymer, used for the design of hydrogels, porous membranes and films. Its solubility in water, film- hydrogel-forming capabilities, non-toxicity, crystallinity excellent mechanical properties, chemical inertness stability towards biological fluids, superior oxygen gas barrier good printability availability (relatively low production cost) are main aspects that make PVA suitable variety applications, from biomedical pharmaceutical uses to sensing devices, packaging materials or wastewater treatment. However, pure present limited flexibility poor biocompatibility biodegradability, which restrict its use alone various applications. mixed with other polymers biomolecules (polysaccharides, proteins, peptides, amino acids etc.), as well inorganic/organic compounds, generates wide PVA’s shortcomings considerably improved, new functionalities obtained. Also, transformation brings features opens door unexpected uses. The review focused on recent advances PVA-based hydrogels.

Dual-Mechanism Tuned Engineered Polyphenols with Cascade Photocatalytic Self-Fenton Reaction for Sustainable Biocidal Coatings

Nano Letters, Journal Year: 2023, Volume and Issue: 23(20), P. 9563 - 9570

Published: Oct. 11, 2023

Traditional disposable personal protective equipment (PPE) only blocks pathogenic bacteria by mechanical filtration, with the risk of recontamination and transmission remaining. Herein, inspired phenolic-enabled nanotechnology (PEN), we proposed engineered polyphenol coatings plant-derived aromatic aldehydes metal involvement, denoted as FQM, to obtain desired photocatalysis-self-Fenton antibacterial performance. Experiments theoretical analysis proved dual mechanism Fe-induced enhancement: (1) tuning molecular structure realized improved optical properties; (2) Fe(III)/Fe(II) triggered photocatalytic cascade self-Fenton reaction. Mechanism study reveals FQM killing direct-contact ROS attack gene regulation. Further, was developed ideal coating on different fabrics (cloth cotton, polyester, N95 mask), more than 93% after 5 cycles use. Such based polyphenols endowed desirable safety, sustainability, efficient features are promising solutions meet challenges currently available PPE.

Hierarchically Nano-Decorated Poly(lactic acid) Nanofibers for Humidity-Resistant Respiratory Healthcare and High-Accuracy Disease Diagnosis

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 19, 2024

The application of biodegradable and eco-friendly poly(lactic acid) (PLA) nanofibrous membranes (NFMs) toward respiratory healthcare has long been thwarted by the poor electroactivity low surface activity PLA. Herein, we unravel a microwave-assisted route to fabricate rod-like ZnO nanodielectrics, which were decorated with dopamine (ZnO@PDA) anchored at PLA nanofibers via an electrospinning-electrospray approach. PLA/ZnO@PDA NFMs featured substantially elevated specific area (up 20.7 m

Tannin-Assisted Synthesis of Nanocomposites Loaded with Silver Nanoparticles and Their Multifunctional Applications

Biomacromolecules, Journal Year: 2023, Volume and Issue: 24(11), P. 5194 - 5206

Published: Sept. 21, 2023

Nanocomposites have been widely used in many important areas due to their particular physical/chemical properties; however, just though a simple technology, endowing multiple functions into single nanomaterial for realizing multifunctional applications is still challenge. Here, we report robust method the facile synthesis of Ag-based nanocomposites via using tannin-coated phenol-formaldehyde resin nanospheres (TA-PFRN) as silver nanoparticle (Ag NP) carriers. The thickness tannin coating readily tuned from 50 320 nm by regulating concentration added. Under optimal conditions, TA-PFRN has 23.8 wt % Ag NPs loading capacity with only 17.2 NP layers. Consequently, novel TA-PFRN@Ag possess and integrated characteristics. As catalysts, catalytic efficiency nearly 6 times higher than that PFRN@Ag. highly effective free radical initiators, can trigger ultrafast acrylic acid (AA)/acrylamide (AM) polymerization at room temperature (in few minutes). nano-reinforced fillers, addition 0.04 improve tensile strength PVA film 60 153.2 MPa. In addition, also serve antibacterial agents, efficiently inhibiting growth Escherichia coli (E. coli) Staphylococcus aureus (S. aureus); antiultraviolet presence endows film/hydrogel materials excellent ultraviolet (UV) shielding.
