Cellulose‐Based Dual‐Network Conductive Hydrogel with Exceptional Adhesion

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(48)

Published: July 25, 2024

Abstract Cellulose consists of a natural, rigid polymer that is widely used to improve the mechanical and water‐holding properties hydrogels. However, its abundant hydroxyl groups make it highly absorbent free water, leading swelling behavior. This increased water content will also decrease adhesive performance. In this study, cellulose successfully hydrophobically modified reduce absorption water. Gelatin then cross‐linked with through Schiff‐base reaction, resulting in bound content. significantly enhances resistance permeability, improves freeze–thaw stability hydrogel. Due internal hydrophobicity, molecules can quickly penetrate into interior, reducing their residence time on hydrogel surface. allows maintain high adhesion natural environments, achieving an strength up 3.0 MPa wood bamboo‐based materials. The retain even after prolonged exposure humid environment. Additionally, Na + ions enhance electrical conductivity sensitivity (gauge factor (GF) = 1.51), demonstrating potential applications flexible sensing.

Fabrication of multifunctional ZnO@tannic acid nanoparticles embedded in chitosan and polyvinyl alcohol blend packaging film

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 9, 2024

The current study explores biodegradable packaging materials that have high food quality assurance, as deterioration is mostly caused by UV degradation and oxidation, which can result in bad flavor nutrition shortages. Thus, new multifunctional zinc oxide nanoparticles/tannic acid (ZnO@TA) with antioxidant antibacterial activities were incorporated into polyvinyl alcohol/chitosan (PVA/CH) composite films different ratios (1%, 3%, 5% based on the total dry weight of film) via a solution blending method neutral aqueous solution. Additionally, ZnO nanoparticles unique mechanisms through generation excessive reactive oxygen species (ROS) may lead to intensify pathogen resistance conventional agents. minimizing negative effects levels ROS be possible developing unique, potential coordination bond between tannic (ZnO@TA). ZnO@TA examined using Fourier-transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM). effect incorporation barrier, mechanical, thermal, antioxidant, antimicrobial, blocking characteristics chitosan/polyvinyl alcohol (ZnO@TA@CH/PVA) was investigated. lowest water vapor permeability maximum capacity% are 31.98 ± 1.68 g mm/m
