摘要：Flame retarded epoxy materials were prepared by blend of HGCP (Hexaglycidyl cyclotriphosphazene) in an organic matrix based on DGEBA epoxy resin. The blends thermoset with 4,4'-methylene-dianiline (MDA) curing agent were characterized by various techniqueswhich consist in thermal by DSC, the morphology by SEM. In electrical characterization it's done with frequency variation range from 100Hz to 100 KHz at room temperature. The rheological behaviour was investigated using small-deformation rheology. These measurements revealed that the reological and electrical behaviours depend strongly on the HGCP amount in DGEBA matrix. The Capacitance-Frequency and conductance-Frequency measurements suggest a distribution of free volume in the blends and select the samples as dielectric materials. The study of linear viscoelastic properties shows that the storage modulus G' is very sensitive to HGCP amount in DGEBA epoxy resin. The as prepared materials seem to be promising materials for electronic compounds
