This study presents the optimisation of the various parameters (wt% of multiwalled carbon nanotube, pore size, size of the middle plate and time of testing) for evaluation of fractional exponent of a solid‐state fractional capacitor. For this, full factorial design of experiments is carried out to understand the crucial parameters, which have an effect on fractional exponent α . Then, contributions of each of the significant parameters are estimated. Later, by one‐way analysis of variance, the combination of various parameters by which one can obtain fractional capacitors of varying α is given in detail. The fractional capacitor for which the optimised design is done has a constant phase angle in between 0° and −90° in the frequency range from 1 to 100 kHz.
