▎ 摘　　要

The current work presents the fabrication of micrometer-thick single-side-coated surface-engineered polypropylene (PP) film for versatile flexible electronics applications. Herein, the authors report, for the first time, photopolymerized thin coating of graphene nanofibers (GNFs) and iron oxide nanoparticles (IONPs) onto non-polar plastic via surface chemistry. The fabrication is achieved by adopting three consecutive steps; initially corona treated PP films are treated with silane for thin layer silica coating. Then, the silylated PP films are brushed up by pyrrole/GNFs/IONPs mixture, followed by UV exposure. The coated films show surface conductivity in the range of approximate to 20 S cm(-1) at room temperature. Moreover, approximate to 15 microns of the coated film is tested against electromagnetic waves in the X-band region (8.2-12.4 GHz) and its shielding behavior (approximate to 24 dB) is confirmed. To demonstrate its wide range of versatility, the coated films are tested against angular strain and oscillatory magnetic fields. The results confirm angle dependent strain sensitivity and induction heating obeying Neel relaxation. To the best of the authors' knowledge, this is the first synergistic coating archived for mitigating radiation pollution, strain sensing, and non-contact heating.
