Design of artificial nacre-like hybrid films as shielding to mitigate electromagnetic pollution

Enhanced flame retardancy of polypropylene by melamine-modified graphene oxide

“…The peaks located at 285.4 and 288.1 eV correspond to the C-N and C=N groups, respectively, in g-C 3 N 4 [45]. The broad peak centered at 290.9 eV can be assigned to the characteristic p-p* shake-up satellite peak of reduced graphene oxide [44]. Four peaks at 398.3, 399.8, 401.0, and 404.5 eV in the high-resolution N 1s XPS spectrum are attributed to the sp 2 -hybridized nitrogen (C-N=C), the tertiary nitrogen bonded to carbon atoms (N-(C) 3 ), the terminal N-H groups, and p excitations [46,47], respectively.…”

“…2b), the decrease in oxygen content is the result of removal of the oxygen-containing groups upon thermal treatment. Figure 5e and f displays the deconvoluted C 1s [44]. The peaks located at 285.4 and 288.1 eV correspond to the C-N and C=N groups, respectively, in g-C 3 N 4 [45].…”

Graphene Nanocomposites for Electromagnetic Induction Shielding

“…6b indicates that thicker shields give more microwave absorption. Yuan et al [90] found that the EMI SE of the PVA/MG film in 0.24 mm thick has an average EMI SE of 15.1 dB in X band, much lower than 20.3 dB for the same film with 0.36 mm thick (Fig. 7).…”

“…In addition, Yuan et al, synthesized γ-Fe 2 O 3 incorporated graphene nanosheets (GNS), then used PVA to blend with GNS via evaporation-induced assembly and obtained PVA/MG hybrid films [90]. In Fig.…”

Hierarchical electromagnetic absorption in micro-waveguide stuffed with magnetic media for resin-based composites of graphene nanosheets and manganese oxides

“…Nowadays, it is important to make effort to minimize electromagnetic interference (EMI) for protecting electronic devices and avoid electromagnetic (EM) pollution in the electronic age [1][2][3]. Because of the existence of EMI, the actual performance of electronic devices becomes poor.…”
