Highly conductive PP/PET polymer blends with high electromagnetic interference shielding performances in the presence of thermally reduced graphene nanosheets prepared through melt compounding

Abstract: In this study, we have prepared highly conductive polypropylene (PP)/poly(ethylene terephthalate) (PET) blends with high electromagnetic interference (EMI) shielding performances by incorporating very low contents of thermally reduced graphene (TRG) through melt compounding method. Based on scanning electron microscopy and transmission electron microscopy images, the blends exhibited co‐continuous morphologies in which TRG nanosheets had been thermodynamically and kinetically driven into PET polymer resulting … Show more

“…Conductive nanocomposites are obtained by dispersing electrically conductive nanoparticles (particles with at least one of their dimensions ranging from 1 to 100 nm) within a matrix. The most used nanoparticles to obtain electrically conductive polymers are carbon black (CB) [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], carbon nanotubes (CNTs) [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 24 , 25 , 26 , 27 , 28 ], and graphene [ 12 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Due to the advantages conductive thermoplastic composites present, significant research has been conducted towards achieving certain desired properties at low filler concentrations, primarily by reducing the percolation threshold (PT).…”

“…[17,[22][23][24][25] Previous studies based on solution casting, in situ, and melt extrusion techniques have been studied with various polymer matrices. [16,[26][27][28][29][30][31] Different investigations have been directed on the electrical, mechanical, and EMI shielding effectiveness (EMI SE) of CNT-polymer nanocomposites. [14][15][16][17][18][19][20][21][22][23] Varrla Eswaraiah et al [27] prepared a novel MnO 2 nanotube (MNT) reinforced PVDF composite, and an EMI efficiency of about -20 dB was achieved with 5 wt% MNT in the X-band region.…”

“…Electrical conductivity in polymer nanocomposites containing conductive nanofiller such as carbon nanotubes (CNT) provides some applications in electronics, shielding, actuating, and sensing . The conductivity of nanocomposites meaningfully improves at a critical concentration as percolation threshold, because the number of nanoparticles at this point is enough to establish the conductive networks .…”
