Debye relaxation model with relative permittivity ( ϵ r ) and logarithm of angular frequency (log ω). The dotted line indicates the angular frequency point in which maximum relaxation time (τ) is encountered by hydrogels. The curves of real and imaginary relative permittivity are symbolized by ϵr′ and ϵr′′, respectively. (GT- gelatin; CT- chitosan; GC0.3-GC3 (gelatin-chitosan in ratio 1:0.3 to 1:3)).
