Highly Thermally Conductive Fluorinated Graphene/Aramid Nanofiber Films with Superior Mechanical Properties and Thermostability

Thermally conductive polymer composites (TCPCs) are in urgent demand for thermal management in modern power electronic systems. However, poor mechanical properties and low heat resistance (<200 °C) restrict their practical applications. Herein, a mechanically strong and highly thermostable fluorinated graphene/aramid nanofiber (f-G/ANF) film was developed by utilizing one-dimensional (1D) ANFs as reinforced blocks and two-dimensional (2D) f-G as...
