Development of phosphazene imine‐modified epoxy composites for low dielectric, antibacterial activity, and UV shielding applications

In this work, phosphazene modified imine was prepared and its molecular structure was confirmed using FTIR and ¹H NMR analysis. The modified phosphazene imine (PZ imine) of different weight percentages was incorporated into DGBEA epoxy resin to obtain composites and the formation of composites was confirmed by FTIR analysis. The composites were subjected to thermal, radiation resistant, electrical, and antibacterial studies. Data resulted from thermal, UV absorption, antibacterial, and surface behavior studies indicate that PZ imine reinforced epoxy composites possess higher thermal stability, enhanced zone of inhibition, better UV shielding, improved hydrophobic behavior and lower value of dielectric constant than those of neat epoxy matrix. The morphology of the samples was analyzed using high resolution transmission electron microsope (HRTEM), which ascertained the homogeneous dispersion of PZ imine in epoxy matrix with fibrous structure.
