“…Furthermore, to attenuate both electric and magnetic part of EM waves; the canvas for fillers is certainly broadened. In this regard, carbonaceous and ferritic fillers are most sort out materials mainly due to their ability to interact with EM waves and attenuate the electric and magnetic parts respectively [10]. Earlier the most followed route for polymer composites was to disperse either metallic or carbonaceous particles to impart the EMI shielding properties.…”

Hybrid polymer composites based on poly vinylidene fluoride (PVDF) matrix are fabricated by dispersion of few layered graphene (FLG) and nickel spinal ferrites (NSF) for improving EMI shielding effectiveness. The FLG loading is kept constant at 3 wt% while NSF content is varied from 15-30 wt% in PVDF using solution processing technique. The shielding effectiveness in the frequency domain of 1-12 GHz is enhanced ranging 25 dB-45 dB for PVDF/FLG composite as compared to ∼0 dB for neat PVDF. With addition of NSF up to 15 wt%, the attenuation is increased to 30 dB-53 dB, clearly indicating the effective interaction and network formation of FLG and NSF in PVDF matrix. Moreover, the shielding effectiveness trend is reduced to 12 dB-43 dB as the NSF loading is increased to 30 wt% owing to its agglomeration. Absorption is the dominant phenomena in obtaining the total shielding effectiveness of ∼53 dB for PVDF/FLG-3 wt%NSF-15 wt% hybrid polymer composites. Additionally, the I-V curves provide the electrical conductivity trend while scanning electron microscope (SEM) confirms the network formation in hybrid composite.

“…Additionally, stretchable and flexible electronics have drawn increasing attention in the industry, because the stretchability will significantly expand the application range of electronics [1][2][3]. Stretchable and flexible conductors are the key to fabricate next-generation stretchable electronics such as stretchable light-emitting diodes (LEDs) [4,5], stretchable displays [6,7], electronic skin [8,9], strain sensors [10][11][12][13][14], electromagnetic interference (EMI) shielding absorbers [15][16][17] and gun propellant [18].…”

Integrating the topology design and printing method offers a promising methodology to realize large stretchability for interconnects. Herein, eco-friendly and waterbased Ag nanowires (NWs) inks were formulated and used for screen-printing highly stretchable and flexible interconnects on a large area (more than 335 mm × 175 mm). The stretchability of the interconnects was realized by introducing kirigami topology structures. The topology designed models were established to simulate the influence of kirigami patterns on wire compliance and to estimate the maximum stretchability via finite element analysis (FEA). The mechanic mechanism results demonstrate that an increase of the wave numbers results in larger stretchability, and the rectangular type of wave shows better stretchability than the zigzag and sine structures. Comparatively, the electrical and mechanical properties of the interconnects were measured and analyzed, and the experimental results were consistent with FEA. The electric conductivity of the interconnects is stable at~10,427 S cm −1 even after 1000 cycles of 15.83 mm radius bending, 280% stretching and 200% twisting-stretching deformation, demonstrating outstanding mechanical reliability of the interconnects. The topology designed interconnects have been applied in stretchable flexible light-emitting diode, indicating their broad application prospects in next-generation stretchable electronics.

The electrical conductivity and electromagnetic interference (EMI) shielding effectiveness (SE) can be conspicuously enhanced at low conductive filler contents with the formation of segregated structure in the conductive polymer composites (CPCs). Nevertheless, poor interface adhesion of segregated composites results in poor mechanical properties due to the selective distribution of conductive fillers. In this work, a flexible approach was applied to fabricate the poly(phenylene sulfide)/poly(arylene sulfide sulfone)/graphene nanoplates (GNPs) composite with a unique double percolated structure. This composite exhibits an outstanding EMI SE of 38.8 dB with only 3 wt % GNPs, which is comparable to that of the conventional segregated structure counterpart. What is more, the tensile strength and Young's modulus of double percolated composites with 3 wt % GNPs are remarkably improved by ~892 and ~274% compared to conventional segregated structure, achieving 37.7 and 1788.3 MPa, respectively. This work provides a valuable method for producing CPCs with high EMI shielding performances and outstanding mechanical properties. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
