Abstract:Bacterial cellulose (BC) is produced by some kind of acetic acid bacteria. BC demonstrates unique properties, including upward mechanical strength, superior crystallinity, high-water holding and elevated porosity, which make it every useful biomaterial in many different progressive processes. Nowadays, several research areas in industrial zones are concentrating to fabricate some applicable product from this biomaterial. However, dimension (size and shape) of BC makes a challenge and must be controllable and invariability in repetition experiments. Therefore, in this study, we present one method identify of BC time growth. We investigated the time duration and air rate factors on our bacterial cellulose samples while other conditions are kept changeless. The outcomes show, producing bacteria cellulose can be independent of the time, whilst the air is remained constant. This approach makes several advantages such as interchangeable samples, invariability BC thickness and cost variables in recapitulation investigations.

Cyclic voltammetry based on an electrochemical technique is one of the current methods that measure the developments of the electrochemical properties in biomaterial samples under conditions. Biomaterial structure was changed by conductive material while these materials caused a connective network in whole of them and was able to transfer electrons inside of biomaterials. These changes in physical and chemical properties are investigated by analysis tools such as cyclic voltammetry (CV), X-radiation (XRF) and Ultraviolet-visible spectroscopy (UV-Vis). Bacterial cellulose is biodegradable, biosynthesis of A. xylinum which is a three-dimensional nano-network structure with a distinct tunnel and pore structure. In this study, the composite process produced electrically conducting bacterial cellulose pellicles containing well-dispersed and embedded multi-walled carbon nanotubes (MWCNTs) Ionic liquids (ILs), as observed in cyclic voltammetry (CV). For this purpose, we used a special tool, called OriginLab which is an industry-leading scientific graphing and data analysis software. The cyclic voltammetry graph presents the behavior of this composite which consists of a relationship between CNT dispersion, conductivity rate and changes in bacterial cellulose structure. The electrical conductivity of the cellulose/MWCNT composite was found different with respect to CNT dispersion. It was found that the incorporation process was a useful method not only for dispersing MWCNTs-ILs in an ultrafine fibrous network structure, but also for enhancing the electrical conductivity of the polymeric membranes.
