Enhanced understanding of organic solvent transportation in NR-NBR blend reinforced with ferrite nanoparticles: A Comprehensive Investigation

Abstract

Abstract 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.
