Fabrication of ultra-thin, hydrophobic and flexible electromagnetic wave absorber sheets based on nano-carbon/carbonyl iron in a polypyrrole/silicone rubber matrix

A study on microwave absorption properties of polyaniline/nitrile rubber/graphene/Fe3O4 composites with a thickness of 0.7 mm and high flexibility

“…17 This behavior is in good agreement with the previous works. 2,9,17 Here, S4 with the optimum content of the fillers, may employ a quadruple mechanism to dissipate the incident radiation. First, graphene components in the PANI/NBR matrix bond to form a conductive network in which the carriers can make an orientation movement caused by the electromagnetic wave effect.…”

“…Consequently, not only does the PANI/NBR enhance the absorbing ability of the composites, but it also improves the stretchability, elongation, and flexibility. 2,9 Graphene is another widely employed compound for electromagnetic wave absorption due to its appealing conductive loss characteristics. However, given the nonmagnetic nature of graphene, the contribution of the magnetic loss mechanisms in the microwave absorption ability of graphene is negligible, which is not expected for a high impedance matching and attenuation constant.…”

Preparation, characterization, and antibacterial activity of chitosan/silicone rubber filled zeolite, silver, and copper nanocomposites againstPseudomonas aeruginosaand methicillin‐resistantStaphylococcus aureus

“…34 The peak at 896 cm −1 is related to the CH bending out of the plane of the ring of monosaccharides. The bands at 1000-1100 cm −1 are attributed to C O and Si O stretching modes in chitosan and SR. 29,34 The presence of residual N-acetyl groups is identified by the bands at nearly 1645 cm −1 (C O stretching of amide I) and 1325 cm −1 (C N stretching of amide III), respectively. The peaks at around 1423 and 1375 cm −1 are assigned to the CH 2 bending and CH 3 symmetrical, respectively.…”

“…The peaks at around 1423 and 1375 cm −1 are assigned to the CH 2 bending and CH 3 symmetrical, respectively. 29 The characteristic peak at nearly 1637 cm −1 can be related to the presence of Ag nanoparticles. 35 The observed band at 1589 cm −1 corresponds to the N H bending of the primary amine.…”

Dough moulding compound reinforced silicone rubber insulating composites using polymerized styrene butadiene rubber as a compatibilizer

“…The thermal degradation resistance of silicone rubber is the best in all kinds of rubbers [7,8]; silicone rubber also has excellent weather resistance, aging resistance and good electrical insulating properties, which make it irreplaceable by other materials [9]. However, the mechanical properties of silicone rubber are poor [10,11]; the addition of inorganic filler, such as silica, to reinforce rubber composite systems has been researched for several decades [12][13][14][15], thus the need for further research. On the other hand, in recent years scholars at home and abroad have been focusing attention on the research of fiber reinforced rubber composites [16][17][18][19].…”
