“…The results outcome revealed that combined form of MWCNTs and magnetite particles offered better shielding effect than other composites. Based on the previous literatures in this current research to prepare high performance shielding material the TiO 2 particle could select as conductive particle since it has a large dielectric constant of 85, the Fe 3 O 4 could be selected as a magnetic counterpart since it contains high retentivity, susceptibility and coercivity [7,8]. To embed these two particles the natural rubber could select as matrix material since it is abundant, ease of availability, simple manufacturing technique and degradable nature too.…”

This current work aims to prepare a flexible elastomeric microwave shielding composite material with good mechanical and thermal properties by dispersing Fe 3 O 4 and titania hybrid nano-particles. The primary aim of this research work is to prepare a high strength and high thermal stable flexible natural rubber composite with higher wave attenuation coefficient against 'X (8-12 GHz)' and 'Ku (12-18 GHz)' band microwave frequencies. The Fe 3 O 4 -Titania hybrids were prepared using low energy ball milling and the hybridization effect was confirmed using transmission electron spectroscopy. The prepared Fe 3 O 4 -Titania hybrids were surface-treated using 3-Aminopropyltriethoxysilane via wet solution method to avoid agglomeration. The natural rubber flexible composite was made by two-roll milling with recommended process parameters. The mechanical and thermal results showed improved tensile strength, modulus and mass decomposition. The highest tensile strength of 60 MPa was observed for composite contains 1.0 vol% of Fe 3 O 4 -TiO 2 particles. Similarly, the highest thermal stability of 385°C is observed for composite contain Fe 3 O 4 -TiO 2 particles. The X and Ku band microwave attenuation behaviour revealed the highest attenuation of 28.1 dB for 1.0 vol% of Fe 3 O 4 -TiO 2 particle dispersed rubber composite in Ku band frequency. These mechanically toughened thermally stable and high microwave attenuation flexible composites could be used as EMI shielding material at antennae and other telecommunication devices where electromagnetic wave interference creates crucial issues.

“…This is because of the depletion of polarized atoms due to very low relaxation time at high frequency. [ 26,27 ] It is again noted that further additions of 6phr of graphene nanoplatelets and cobalt nanowire offers very high relative permittivity of 7.2 in real part and 7.5 in the imaginary part. This higher permittivity is the cause of the presence of both graphene nanoplatelet and cobalt nanowire.…”

Highly flexible microwave shielding E (2-3 GHz), F (3-4 GHz), I (8-12 GHz) and J (12-16 GHz) natural rubber composites for antenna application were prepared and characterized. The main objective of this current research is to develop a flexible microwave shielding material to reduce electromagnetic inference (EMI) effect. Graphene nanoplatelet and cobalt nanowire was selected for improving electric and magnetic losses. The flexible rubber composite was prepared using two-roll mill process and cured at an temperature of 150 ο C. The mechanical, dielectric, magnetic, and microwave shielding properties were tested in accordance to ASTM standards. Highest tensile strength of 30 MPa was obtained for composite made of 6phr (parts per hundred rubber) of graphene nanoplatelet and cobalt nanowire (NR 4). Dielectric results show that the composite consists of graphene nanoplatelet and cobalt nanowire of 6phr gives highest dielectric constant of 7.2. The hysteresis analysis shows a highest magnetization of 940 emu, remanence of 610 emu and coercivity of 2750G for NR 4 composite. Similarly, the maximum microwave attenuation of 38.1 dB at 18 GHz (J band) was achieved in NR 4 composite. This high microwave shielding flexible composite material could be used as EMI filter and electromagnetic absorber in antennae applications where EMI need to be lesser.

[17][18][19][20][21][22] The popularity of polymer composites with new types of properties has increased, and castor oil has begun to be used in the production of biodegradable polyester. In particular, the fact that castor oil contains hydrogenated, oxidized, halogenated, and polymerizable cis-double bonds enables the production of biodegradable polymer composites.…”

In this research, modified castor oil (MCO)‐based biocomposite has been synthesized and its structure is strengthened with waste polyethylene (PE) reinforcement. Both the petrochemical raw material used is reduced by 12 wt% and a new environmentally friendly biocomposite is produced using waste PE. Considering some thermophysical properties of the obtained biocomposite, experimental working conditions, and composition ratios have been optimized with response surface methodology (RSM). The chemical bond structure of the biocomposite has been investigated by Fourier transform infrared spectrophotometer, thermal decomposition behavior by thermogravimetric analysis, and surface morphology by scanning electron microscopy. According to the results obtained, the density and hardness of the biocomposite synthesized by the addition of MCO to unsaturated polyester (UP) decreases, and its thermal conductivity and thermal stability increase. The thermal decomposition kinetics of the biocomposite is also modeled with the newly improved hyperbolic function equation. The relationship between conversion rate and the temperature has been determined by the new model with a high correlation coefficient (R2 = 0.9985) and low‐error functions (SST = 0.0096, RMSE = 0.0285, χ2 = 0.0037). Effective and efficient use of MCO, UP, methyl ethyl ketone peroxide, and cobalt octoate in the production process has provided an economical and steady the biocomposite. Evaluation of experimental data with both RSM and artificial neural networks raises the reliability of the model results.
