Preliminary research on structure and properties of nano-cellulose

Abstract

The structure of bacterial cellulose (BC) produced by Acetobacter xylinum NUST⁴ (A.xylinum NUST⁴) under static (SBC) and shake culture condition (ABC) was studied by means of transmission electron microscopic (TEM), X-ray diffraction (XRD) and Fourier transform-infrared spectrum (FT-IR). It was revealed that BC is I crystal cellulose and the proportion of cellulose I_α exceeds 80% and BC diameter is 10–80 nm. Mechanical properties and water absorption capacity were also determined. These properties could result from crystalline and nanometer structure of BC.
