Experimental Study on Polymer Nanocomposites Based Strain Sensors for Structural Health Monitoring

The aim is to develop a mechanically flexible polymer nanocomposite film-based strain sensors that could act towards sustainable structural health monitoring for civil structures. developed film combinations will be monitored their structural, electrical and mechanical behaviors the optimized formulations tried sensing applications. films were cast by using PVA as base copper doped silver nitrate nanofiller along with use of glycine fuel which combination nitrate. After preparing films, they tested conductivity under tensile loading digital multi meter connected UTM. samples subjected XRD, FTIR SEM further analysis. results experiments shown I-V characteristics PVA-CuAgO composites from 5% 25% CuAgO have been increased tremendously incorporation filler material. For 100 V, maximum current value obtained plain only 7.7E-8 A, whereas particles 0.0025 A at reinforcements nearly 0.025 into matrix.
