▎ 摘　　要

Thermal behavior of polyester composite with graphene oxide/graphite was investigated using DMA, TGA and SEM. The influence of graphene oxide/graphite on mechanical and thermal properties of polyester composites were studied in case of small contents. The study allowed to conclude that graphene oxide and graphite have a different effect on polyester composites due to their different chemical bonds with polyester matrix. Analytical inference of the storage modulus was done using Einstein relationship, while the Nielsen equation was used for the damping factor. Glass transition temperature of polyester composites was inferred by DMA method. Thermal stability and mass loss were investigated through TGA tests. Images obtained by scanning electron microscopy allowed morphological analysis of the composite specimens.
