Abstract
The past two decades have expressed very advanced industrial utilities of smart thermoplastic composites for pressure sensing, aerospace, welding of dissimilar polymers, structural monitoring, 3D printing, and so on. Nevertheless, very little work has been reported on 4D printing of smart thermoplastic composites for sensing features based on online health monitoring (OHM) applications. This work highlights some of the investigations performed on dielectric properties of polyvinylidene fluoride (PVDF) based on various smart thermoplastic composites for OHM applications in structural and nonstructural engineering. The experimentations performed on a self-actuating smart composite matrix of PVDF have been observed as an innovative solution for the preparation of smart repair solutions for nonstructural cracks in heritage structures. To date, the 4D printing-based properties of such compositions are the least reported for smart sensor fabrication with OHM capabilities. As an extension to the previously reported studies on PVDF composite matrix-based smart customizable solutions (for the repair of heritage buildings), this study outlines the experimental trials performed on the effect of dielectric properties of smart thermoplastic composites for OHM of heritage structures. The outcomes of the work show that dielectric properties of the compositions (governed by rheological properties) have a significant effect on mechanical, thermal, morphological, and shape memory properties for OHM of repaired heritage structures. The multifactor optimization has been performed to ascertain the acceptable composition of polymer composites for efficient dielectric property-based sensor fabrication for health monitoring applications.
