“…The transmission (T), absorption (A) and reflection efficiency (R) of the composites are calculated according to the electromagnetic shielding formula. Consequently, the reflectivity increases from 0.48 to 0.79 with the increase of filler content as shown in 3.7 (d) [ 25 , 37 ]. Therefore, it can be inferred that the modified GnPs@Ni/PPSU composite was high-performance reflection-dominated electromagnetic shielding material [ 38 ].…”

First, nickel particles were deposited on the surface of graphite nanoplatelets to fabricate highly conductive GnPs@Ni core-shell structure hybrid fillers via electroplating. The modified GnPs were blended with polyphenylene sulfone via the solution blending method, followed by the hot-pressing method to achieve high thermally conducting GnPs@Ni/PPSU composites for high performance electromagnetic interference effectiveness. The results showed that in-plane and through-plane thermal conductivity of the composite at the 40 wt% filler loading could reach 2.6 Wm−1K−1 and 3.7 Wm−1K−1, respectively, which were 9.4 and 20 times higher than that of pure PPSU resin. The orientation degree of fillers was discussed by XRD and SEM. Then, heat conduction data were fitted and analyzed by the Agari model, and the heat conduction mechanism was further explored. The testing results also demonstrated that the material exhibited good conductivity, electromagnetic shielding effectiveness and superior thermal stability. Overall, the GnPs@Ni/PPSU composites had high thermal conductivity and were effective electromagnetic shielding materials at high temperatures.

“…8,9 Recently, the demand for lightweight EMI shielding materials has been increasingly strong, especially for many emerging areas such as aircraft, spacecraft, automobiles, portable devices, etc. [10][11][12][13] Rational design of porous structures with a high specific surface area can not only realize the lightweight of EMI shielding materials, but also provide more space for multiple internal reflection and scattering of electromagnetic waves, so as to attenuate more electromagnetic energy. [14][15][16] For lightweight shielding materials, their EMI shielding performance is usually evaluated by the absolute EMI shielding effectiveness (SE) value (SSE/t, SE divided by the density and thickness of the sample), which incorporates three factors: EMI SE, density and thickness.…”

In this study, styrene‐maleic anhydride copolymer/chlorinated polyvinyl chloride composite membranes were prepared via a non‐solvent induced phase separation technique. Different porous morphologies of the composite membranes were obtained by controlling the temperature of coagulation bath water. With the coagulation bath temperature increasing, the porous morphology of membrane surface changed from co‐continuous pores to isolated‐round‐pores, and its evolution mechanism was elaborated. The average pore size of membranes surface increased from 17.27 to 48.72 nm, the pure water flux increased from 225.50 to 624.47 L m−2 h−1, and the rejection rate of Congo red and bovine serum albumin declined gradually with the increase of coagulation bath temperature, but the NaCl rejection was less than 1.0%. The surface segregation behavior of anhydride groups was affected by the phase separation process, which in turn affects the anti‐fouling performance of membranes. The composite membranes obtained at the coagulation bath temperature of 20 and 30°C had large surface segregation of anhydride groups and excellent anti‐fouling performance. The water flux recovery rate is higher than 90% and the irreversible pollution decline rate is about 5.0%. Meanwhile, the obtained membranes, especially the membrane fabricated at a coagulation bath temperature of 0°C, has good dye/NaCl salt separation performance and can be used for the pretreatment of textile wastewater.
