The logical outline and assembly of structural�functional materials are a progressive tendency of materials knowledge. The high specific surface areas and superior properties of graphene (Gr) spread in low-density polyethylene (LDPE) considerably improved the thermal stability and conductivity of LDPE/Gr composites. The electrical conductivity upgraded owing to the great thermal strength of Grs in LDPE matrix. Outstanding distribution of Grs was accomplished. LDPE/Gr composites were characterized by scanning electron microscopy, transmission electron microscope, Raman spectra, X-ray diffraction, thermogravimetric analyses and differential scanning calorimeter for studying the distribution, morphology and thermal strength of Gr composites. Results display that the presence of filler does not create an alteration in the microscopic structure of polymers. However, on a macroscopic scale, addition of Gr improved significantly the thermal and electrical properties of all LDPE/Gr compounds. © 2018, Central Institute of Plastics Engineering & Technology.
