聚乙烯醇/石墨烯纳米复合材料的电阻式应变传感性能研究
Study on Resistive Strain Sensing Performance of Polyvinyl Alcohol/Graphene Nanocomposites
摘要
Abstract
Polyvinyl alcohol(PVA)was used as the matrix and reduced graphene oxide(rGO)was employed as the conductive filler to prepare PVA/rGO nanocomposite films via a solution blending-casting method.The structure and thermal properties of the composite films were characterized,and the effects of rGO content on the mechanical properties,electrical conductivity,and resistive strain-sensing performance of the composites were systematically investigated.The results showed that rGO could form a uniform conductive network within the PVA matrix.At an rGO mass fraction of 2.0%,the composite films exhibited an electrical percolation threshold of approximately 0.75%,a tensile strength of 65.2 MPa,and strain gauge factors of 5.5 in the strain range of 0～10%and 18.0 in the range of 10%～50%.After a test of 500 stretching cycles,the signal drift was below 3.5%,and the response time was approximately 80 ms.The PVA/rGO-2.0%composite films demonstrated excellent strain-sensing performance and cyclic stability,indicating potential application in flexible wearable sensors.关键词
