摘要：
The structure, composition, and thermophysical properties of a PTFE composite with few-layer graphene nanoplatelets have been studied by IR spectroscopy, Raman spectroscopy, and differential scanning calorimetry. Small addition of graphite nanoplatelets (2-6 wt %) have been shown to increase the melting point, enthalpy of melting, and degree of crystallinity of PTFE. This effect is attributed to the fact that graphene nanoplatelets serve as centers of additional crystallization of PTFE from the mixture.
