In-situ Photochemical Synthesis of Novel Silver Nanoparticles-Polymer Composites as High K Polymer Matrix for Embedded Passives Applications

摘要

In-situ synthesis of Ag nanoparticles was successfully carried out in various epoxy matrix by photochemical method. The effects of reducing agent type, concentration of metal precursor, epoxy matrix type and additives on the morphology of nanoparticles were explored. Transmission electronic microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the microstructure of the in-situ formed Ag nanoparticles within the epoxy matrix, called as Ag-epoxy mixture which can be used as a high-K polymer matrix. The dielectric properties of the Al/Ag-epoxy composites were studied and compared with the Al/epoxy composites.
