“…Magnetic sensors and seals used in aviation systems are applications for NR-NBR blended ferrite composites in the aerospace sector. These composites can survive temperature fluctuations during flight while maintaining their magnetic characteristics [16]. Therefore, this study aims to evaluate the barrier properties of this material and gain a deeper comprehension of its absorption behaviour concerning organic solvents [17,18].…”

The research paper examines the transport of three regularly used laboratory organic solvents with varying solubility parameter values over a polymer blend nanocomposite membrane generated by two-roll milling. The three solvents employed (hexane, toluene, and ethanol) have varying solubility parameters. The study aimed to determine how solubility affects diffusion transport parameters in NR/NBR blends. The study indicated that incorporating magnetically active ferrite material decreased solvent absorption, diffusion, sorption, and permeation constants at lower loading. The transport method of NR/NBR nanocomposites was discovered to be unusual. Different solubility values significantly impact transport qualities. Morphological analysis data supports the relationship between ferrite content and other characteristics. The study analysed the influence of blend ratio, size of solvent molecule, and ferrite loading on the diffusion of aromatic and aliphatic solvents within NR/NBR blended systems. Including fillers' reduced swelling coefficient values, indicating a blocked solvent diffusion channel into the polymer matrix. Lower filler loading improved reinforcement, as validated by cross-link density and mechanical qualities. Data on transport was used to develop mathematical models to predict diffusion behaviour and understand the physical process of transport over nanocomposite membranes.

The Zn0.5Cu0.5Fe2O4 nano ferrites were prepared by the solution combustion method using aloe vera gel. The polyaniline-Zn0.5Cu0.5Fe2O4 nano ferrite composites were prepared by Ex-situ polymerization method with different weight percentage ratio. The prepared samples were examined by X-Ray diffraction, SEM, EDAX, BET, TEM, VSM and Impedance analyser to investigate their structural, morphological, elemental analysis, average pore size and the porosity, magnetic, and dielectric properties, respectively. The cubic spinel structure was confirmed by X-ray diffraction patterns. Addition of PANI to zinc-copper nano ferrite exhibits shift in crystalline peaks towards larger angle. The existence of spherical and clumped particles was revealed by SEM examination. The retentivity and coercivity are determined and the magnetic moment values were decreases with increase in PANI to the ferrite nanocomposites. The ac conductivity constant at lower frequency and there is a sudden increase and decrease in its value as a function of frequency shows resonance behaviour. The CZF-1 (CZF 30%) composite shows highest ac conductivity and dielectric constant. The electromagnetic shielding interference studies were conducted for S-band frequency. The CZF-1 (CZF 30%) nano composite shows highest shielding effectiveness as compared to other composite in the frequency range 2 to 3 GHz. The experimental result showed that these materials are used for applications in electromagnetic interference shielding.
