The complex dielectric permittivity of hydroxypropyl methyl cellulose (HPMC)-water mixture was measured by using Time Domain Reflectometry (TDR) and Frequency Domain (LCR) Technique at 25 ° C. The complex dielectric permittivity ε*(ω), complex electrical modulus M*(ω), complex electrical conductivity σ*(ω), loss tangent (tanδ), static dielectric constant (ε0) and relaxation time (τ) have been determined for the cellulose-water system.

The complex dielectric permittivity ε*(ω), complex electrical modulus M*(ω), complex electrical conductivity σ*(ω), loss tangent (tanδ), static dielectric constant (ε0) and relaxation time (τ) have been determined for the cellulose-water system.
