Abstract: Background: The addition of nanofillers to polymers for enhanced performance is deliv-ering more interesting applications for aerospace, aeronautic industries, and other numerous nano-technical applications.
Objective: The aim was, therefore, to examine the role of graphene nanopowder on the thermal
stability and conductivity of the poly(vinyl alcohol)/poly(vinyl pyrrolidone) (PVA/PVP) polymer
nanocomposites.
Methods: In this work, graphene nanofillers were incorporated into the PVA/PVP polymer blended
by solution mixing for the preparation of nanocomposite films.
Results: Results showed that increasing graphene ratio improved thermal conductivity up to 330%,
moreover enhancing hardness shore A up to 16.3% compared to pure PVA/PVP blend polymer.
TGA analysis confirmed that the PVA/PVP and graphene network showed good thermal stability.
Conclusion: From the present findings, it is proved that PVA/PVP blends have profound effects on
thermal stability that cannot be attained by using individual counterparts. The property of the nano-composite depends on the host blend, morphology, and interfacial characteristics.
