MXene增强型导电水凝胶的快速制备及其在柔性可穿戴传感器中的应用
Rapid Preparation of MXene-Reinforced Conductive Hydrogels and Its Application in Flexible Wearable Sensors
摘要
Abstract
To address the issues of long preparation time and the difficulty of simultaneously responding to large-scale deformation and micro-scale stimulation for matrix materials of flexible wearable sensors,this study constructed a conductive hydrogel composed of polyvinyl alcohol(PVA),tannic acid(TA),and MXene nanosheets.The hydrogel could gel within 10-30 s at room temperature by simple physical mixing.The mechanical properties,electrical conductivity,and microstructure were characterized by rheological tests,electrical measurements,and scanning electron microscopy,while the self-healing behavior was investigated through damage-repair experiments.The results showed that the hydrogel exhibited an elongation at break exceeding 600%,achieved self-healing within 10 s,and attained an electrical conductivity of up to 0.513 S/m.The introduction of MXene promoted the formation of a continuous conductive network,enabling the material to generate stable electrical signals in response to large-scale deformation such as finger bending and muscle contraction,as well as distinguishable responses to micro-scale stimulation including blowing and water droplet impact.This hydrogel combined rapid preparation,favorable mechanical properties,electrical conductivity,and cross-scale sensing capability,making it suitable for flexible wearable sensors.关键词
