Dielectric and Acoustic Response of Biocellulose

Abstract

The results of dielectric response studies of the biocellulose show that two relaxation processes can be distinguish: the local main chain motion at ∼200 K and an orientational motion in a mixed phase of polysaccharide and water at ∼325 K. The electroacoustic parameters of a loudspeaker with biocellulose membrane were measured in echoless conditions. The relationship between dielectric and mechanical properties of biocellulose was found.
