Scalable ultrarobust thermoconductive nonflammable bioinspired papers of graphene nanoplatelet crosslinked aramid nanofibers for thermal management and electromagnetic shielding

Abstract: Graphene nanoplatelets are chemically crosslinked to aramid nanofibers through a phosphorus trimer to fabricate ultratough, thermoconductive, flame retardant, and EMI shielding films.

“…Graphene-based polymer composites can possess extremely high thermal conductivity and mechanical enhancement. However, the intrinsic high electrical conductivity significantly limits their application as dielectrics and electrical insulation. With both ultrahigh thermal conductivity and excellent electrical insulating property, boron nitride (BN) is believed to have enormous potential as thermal conductive filler of dielectric polymer composites …”

“…As the structure of a material always determines its properties, structural design and controlling without sacrificing other merits are of great significance for realizing high-performance EMI shielding [20][21][22][23][24]. Recent researches have verified that various types of structures that are beneficial to EMI shielding are successfully constructed [25][26][27][28][29]. Therein, segregated structure is able to concentrate conductive fillers together to build conductive networks in polymer matrix, which accordingly reduces the conductive percolation threshold [30][31][32][33][34].…”

“…The remarkable mechanical properties of ANF/PVA/BNNS-OH composite films could be attributed to their favorable interfacial interactions and well-arranged architecture. 58 XPS surveys of composite films were carried out to explore the interfacial interaction between BNNS-OH and ANF/PVA frame, as shown in Figure S3a−c. Compared to the ANF/PVA, the high-resolution N 1s spectra of ANF/PVA/BNNS-OH can be deconvoluted into two distinct peaks, corresponding to the nitrogen atoms of N−H (∼399.5 eV) and interfacial hydrogen bonding of −N•••H (∼397.6 eV), 59 which provide compelling evidence for excellent interfacial interaction in the composite film.…”
