“…Therefore, there is a need to reinforce PU with other material which easily conducts electricity and heat as well does not adversely affect the quality of the polymer matrix [22–24] The PU‐based nanocomposites or similar PNCs are formed by using different nanofillers such as metallic nanoparticles; carbon‐based nanomaterial (CBNs) including carbon dots, carbon nanotubes and graphene; clays such as montmorillonite, nano‐silica; and so on [25,26] . Among all these nanomaterials, graphene (Gr) is one of the most suitable nanofillers for the fabrication of PNCs owing to its different physicochemical properties such as large surface area, thermal and electrical conductivity, high electron mobility, thermal stability and optical transparency [27–29] . By incorporating Gr into PU, a synergistic effect can be achieved, leading to the development of PNCs with enhanced functionalities and expanded potential applications.…”
