铁离子配位增强的聚乙烯醇-羧甲基纤维素钠多网络水凝胶及其在柔性传感与心电监测中的应用
Fe3+coordination-enhanced polyvinyl alcohol-sodium carboxymethyl cellulose multi-network hydrogel for flexible sensing and electrocardiogram monitoring
摘要
Abstract
In order to achieve the synergistic optimization of the mechanical properties and electrical conductivity of polyvinyl alco-hol(PVA)hydrogels,we used PVA and sodium carboxymethyl cellulose(CMC)as hydrophilic matrices and combined with Fe3+ions to construct a multiple cross-linked network.Through ion complexing method,the PVA-CMC/Fe3+multi-network hydrogel was pre-pared.Systematic characterization confirmed that Fe3+could not only enhance the mechanical strength,as a cross-linker but also signifi-cantly improve the electrical conductivity.The test results showed that the optimized PVA-CMC-0.2Fe3+hydrogel exhibited a tensile strength of 112.66 kPa and an electrical conductivity of 3.03 S/m.This hydrogel has high sensitivity and stability,can be assembled as flexible sensors for monitoring human joint movements and electrocardiogram(ECG)signals.关键词
