Abstract

This paper develops two equations for relaxation time and storage modulus of biopolymer nanocomposites at unlike frequency ranges. The relaxation time is correlated to zero complex viscosity, yield stress, K constant and power-law index. In addition, the blends and nanocomposites of biopolymers and carbon nanotubes (CNT) are fabricated and their complex viscosity and storage modulus are characterized. The experimental results of relaxation time for the organized specimens are linked to the calculations. Also, a model is suggested for storage modulus by yield stress, relaxation time, zero complex viscosity and power-law index. The significances of various parameters on the relaxation time and storage modulus are determined and vindicated to authorize the established equations. The model's guesstimates acceptably follow the investigational results of relaxation time representing the predictability of the advanced model. Both yield stress and K directly manipulate the relaxation time. Moreover, a low zero complex viscosity and a big power-law index increase the relaxation time. The yield stress, relaxation time and zero complex viscosity directly govern the storage modulus, but the power-law index plays an adverse role. © 2021 The Author(s).
