Effect of Sucrose Amounts on the Bacterial Cellulose Membrane's Breathability Properties

Abstract

This study aims to produce a bacteria cellulose (BC) membrane. The critical parameter controlled in this study was the amount of carbon source during the production. The effects of carbon source concentrations on BC membrane properties, such as yield, thickness, and breathability, were evaluated. The BCs' yields and thicknesses were increased with the higher concentration of sucrose utilised during the production process. By weighing and observing the BC membranes, sample BCS10.0 possessed the highest yield and thickness. Nonetheless, the lowest yield and thickness of BC membrane (1.374%, 0.07mm) produced a high mean pore diameter (16.909Å) and increased permeability of water vapour (4242.23g/m2/day).
