Abstract

Despite the state-of-the-art advantages of cellulose in improving the quality of electrical and electronic materials, this natural material does not always bring positive effects. The present work aims at filling this gap. For this purpose, a novel ferroelectric nanocomposite based on a classical ferroelectric metal-organic framework of dimethylammonium aluminum sulphate hexahydrate with a dielectric inclusion of cellulose nanoparticles was synthesized. The study on structure and dielectric properties revealed that the cellulose caused a strong depression of ferroelectricity at temperatures of lower than 115 K when interacting with functional groups of the ferroelectric component.
