Abstract
ABSTRACT Time Domain Reflectometry (TDR) and frequency domain techniques have been used for the dielectric measurement of methyl cellulose (MC) with water for different concentrations and frequency ranges from 20 Hz to 2 MHz and 10 MHz to 30 GHz at 25°C. The dielectric relaxation in these mixtures can be represented by the Debye relaxation behaviour. The dielectric parameters such as complex permittivity ε*(ω), complex electrical modulus M*(ω), complex electrical conductivity σ*(ω), loss tangent (tan δ), static dielectric constant (ε0) and relaxation time (τ) have been determined. The variation of dielectric parameters of methyl cellulose (MC) in water suggested that methyl cellulose (MC) bonds with water alter its structure and electric dipole moment.
期刊介绍：
Physics and Chemistry of Liquids publishes experimental and theoretical papers, letters and reviews aimed at furthering the understanding of the liquid state. The coverage embraces the whole spectrum of liquids, from simple monatomic liquids and their mixtures, through charged liquids (e.g. ionic melts, liquid metals and their alloys, ions in aqueous solution, and metal-electrolyte systems) to molecular liquids of all kinds. It also covers quantum fluids and superfluids, such as Fermi and non-Fermi liquids, superconductors, Bose-Einstein condensates, correlated electron or spin assemblies.
By publishing papers on physical aspects of the liquid state as well as those with a mainly chemical focus, Physics and Chemistry of Liquids provides a medium for the publication of interdisciplinary papers on liquids serving its broad international readership of physicists and chemists.
