HEC/PEDOT:PSS增强增韧水凝胶的构筑及传感应用
Construction of HEC/PEDOT:PSS Reinforced Toughened Hydrogels and Sensing Applications
摘要
Abstract
A HEC/PEDOT:PSS composite conductive polymer was synthesized via in situ polymerization using water-soluble hydroxy ethyl cellulose(HEC)as a template,poly(3,4-ethylenedioxy thiophene):polystyrene sulfonate(PEDOT:PSS)as the conductive complex,which was subsequently incorporated with polyacrylamide(PAM)to construct a hydrogel system.Within this system,the abundant hydroxyl groups present in HEC are capable of promoting the growth of PEDOT,while the regulation by sulfuric acid and PSS resulted in excellent dispersion and uniformity of the polymer.The HEC/PEDOT:PSS/PAM hydrogel was ultimately obtained through chain entanglement and multiple hydrogen bonding interactions.Zeta potential of the HEC/PEDOT:PSS was-34.5 mV.When the mass fraction of HEC reached 0.75％,the hydrogel demonstrated a tensile strength of 0.34 MPa,elongation at break of 814％,and toughness of 1.19 MJ/m3,representing enhancements of 1.62,1.27,and 3.41 times respectively compared to the conductive hydrogels without HEC template.Additionally,the hydrogel exhibited a gauge factor of 7.20 and response interval of 41 ms,demonstrating both mechanical robustness and sensing sensitivity.关键词
