Down‑Top Strategy Engineered Large‑Scale Fluorographene/PBO Nanofibers Composite Papers with Excellent Wave‑Transparent Performance and Thermal Conductivity (IMAGE)
Caption
- The down-top strategy enables large-scale production of poly(p-phenylene benzobisoxazole) nanofiber (PNF) paper with excellent intrinsic wave-transparent performance, thermal conductivity, and mechanical strength while significantly reduces the preparation time and cost.
- Fluorinated graphene (FG)/PNF composite papers exhibit superior wave-transparent performance and thermal conductivity. When the mass fraction of FG is 40 wt%, its |T|2 reaches 96.3% under 10 GHz while λ∥ and λ⊥ increase to 7.13 and 0.67 W m-1 K-1, respectively.
- FG/PNF composite paper with 40 wt% of FG also displays excellent mechanical properties, with the tensile strength and toughness reaching 197.4 MPa and 11.6 MJ m-3, respectively.
