- •
A comprehensive analysis of the thermal conductivity of graphene under various conditions is presented in this study.
- •
Results obtained from different experimental and theoretical methods are analyzed and discussed for numerous conditions such as preparation process, shape, sample size, wavelength, and temperature.
- •
Large differences in the values of the thermal conductivity of graphene were noticed from the cited results using different experimental and numerical methods (0.14 W/m K–20,000 W/m K).
- •
Accuracy of these methods when measuring thermal conductivity of graphene at nanoscale became questionable.
- •
We have established the existence of a high degree of anomalies in the value of the thermal conductivity of grapheme.
