“…Formation of PDA on the surface of graphene oxide incorporates heterogeneous nitrogen atoms, creating structural defects that lead to higher ratios. After the mixed acid reduction, the oxygen-containing groups of PGO were removed, resulting in topological defects and vacancies in the graphene lattice, making the ratio larger again. , The chemical structures of GO, PGO, and PRGO are further analyzed by XPS analysis. The XPS survey spectra of GO, PGO, and PRGO are given in Figure c.…”

With the problem of electromagnetic interference (EMI) increasingly serious, the development of lightweight and flexible electromagnetic shielding composite films with excellent Joule heating performance and good mechanical properties is of great significance for modern electronic devices. In this study, we prepared aramid nanofiber/aramid nanofiber-poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)/polydopamine-modified reduced graphene oxide (ANF/APP/PRGO) composite films with excellent electromagnetic shielding properties and electrical heating properties by stepwise vacuum filtration. With high conductivity (124.10 S/cm) and multi-interface electromagnetic wave reflection caused by the layered structure, the composite films achieve an EMI shielding effectiveness (SE) as high as 40.52 dB at 8.2–12.4 GHz (X-band) with a low thickness (∼22 μm). At the same time, the composite films also exhibit excellent electrical heating performance with fast response and cycle stability, which can reach a surface saturation temperature as high as 127.6 °C under an applied voltage of 7 V. Therefore, it can be envisaged that the ANF/APP/PRGO composite films have certain practical application value in the fields of electromagnetic shielding and electric heating.
