Multifunctional MENs doped adhesives for bond quality evaluation
Abstract
In the first phase of this research, magneto-electric nanoparticles (MENs) were used as localelectric-to-magnetic-field nano-conver"ters to remotely monitor the local electric (not justmagnetic) fields and signals that underlie the intrinsic molecular interactions in individual bonds.Optimal diameters and concentrations were determined for the MENs and the concept wasverified by comparing signatures of baseline specimens with signatures of specimens that havebeen environmentally exposed. Significant changes in magnitud"es were observed indicating thatthis method can be utilized to monitor the health of an adhesive bond. In addition, the resultings"trength of the bond was found to have increased up to 20% over the same adhesive that was notdoped with the MENs. In an effort to f"urther verify the validity and usefulness of this technique,five additional task are proposed for the next phase of research:
