摘要:
以聚丙烯酰胺和天然高分子瓜尔胶作为柔性基底，聚吡咯作为导电物质填料，设计制备出一种柔软的导电水凝胶。采用扫描电子显微镜观察水凝胶的截面形貌，通过拉力试验机测试水凝胶的弹性。测试结果表明其具有良好的可拉伸性能：最大拉伸应变为936.4%，拉伸应力为158.9 kPa，并且在对水凝胶进行15次拉伸应变为300%的拉伸-回复测试，水凝胶能回复原状，表明其具有快速的自恢复能力。进一步将水凝胶作为应变传感器监测人体的手指弯曲、手腕弯曲、吞咽等运动，可得到连续、准确且稳定的传感数据。这种多功能性的瓜尔胶/聚丙烯酰胺基导电复合水凝胶可用于可穿戴电子设备、健康和运动监测器等领域。

Abstract:
A kind of soft conductive hydrogel was designed and prepared using polyacrylamide and natural polymer guar gum as flexible substrates and polypyrrole as a conductive filler. The cross-section morphologies of the hydrogels were observed by scanning electron microscopy and the elasticity of the hydrogels was tested by a tensile testing machine. The test results showed that the hydrogels possess good tensile properties with the maximum tensile strain of 936.4% and the tensile stress of 158.9 kPa. After 15 times of tensile-recovery tests at the tensile strain of 300%，the hydrogel can return to its original state，indicating its rapid self-recovery ability. Furthermore， the hydrogel was used as strain sensors to monitor a human finger bending， wrist bending，swallowing and other movements. Continuous，accurate，and stable sensing data can be obtained. This multifunctional guar gum/polyacrylamide-based conductive composite hydrogel is expected to be used in wearable electronic devices， health and exercise monitors and other fields.
