Macromolecular Rapid Communications, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

Abstract In order to improve the disadvantages of traditional hydrogels such as low mechanical strength and lack responsiveness, different types nanoparticles or nanostructures are added into hydrogel network through in situ polymerization, self‐assembly techniques, other strategies, giving a variety special properties, stimulation sensitivity, optical electrical reversibility. With development nano materials synthesis technology, nanocomposite have shown great potential drug delivery, tissue engineering, motion detection, wastewater treatment, been extensively studied recent years. This review comprehensively elucidates state‐of‐the‐art preparation strategies underlying response mechanisms diverse stimulus‐responsive hydrogels, spanning temperature, pH, humidity, electrical, light responses. It systematically dissects their applications biomedicine, environmental remediation, flexible sensing, composite phase change materials. Moreover, it delves future prospects challenges, emphasizing need for continuous innovation unlock full emerging fields address existing limitations.

Investigation of electrochemical characteristics of intergel systems based on polyacrylic acid

Chemical Journal of Kazakhstan, Journal Year: 2024, Volume and Issue: 1, P. 5 - 16

Published: March 15, 2024

Currently, hydrogels are polymer materials in high demand due to their physicochemical properties, and recent years have seen significant attention given the study of properties [1,2]. The purpose this research is investigate effect remote interaction on electrochemical intergel systems containing polyacrylic acid, poly-4-vinylpyridine, poly-2-methyl-5-vinylpyridine, polyethyleneimine with various initial states. dependency conductivity pH levels aqueous solutions was examined. obtained results shown thatin 5:1 ratio PAAswollen:P4VPdry system, medium reaches its maximum value after 24 hours, a corresponding decrease level. For PAAdry:P2M5VPdry at ratios 5:1, 1:5, 2:4, electroconductivity observed sixth hour. achieved 4:2, indicating low presence nitrogen heteroatoms solution. PAAswollen:PEIswollen system 3:3 reached 8.5 while showed minimum value. In PAAdry:PEIdry decreased over time all hydrogel ratios. An exception noted 4:2 ratio, where slightly increased 0.5 then fell again, showing deviation from general trend. Conclusion. conducted has that specific varies across molar hydrogels. It established changes pairs states affect conductivity, ionized dissociated groups chain normally. These demonstrate these can be used get high-selectivity sorbents.
