Abstract

The preparation method of cellulose films plays a vital role in their properties. This work aims to characterize 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized bacterial cellulose powder (TOBCP) films prepared with three different methods (casting, boiling-casting, and boiling-vacuum). It is found that film by casting (CT film) shows the best electrical properties. A light-emitting diode (LED) in a direct current circuit connected to the CT film glows the most brightly. However, this film had lower tensile strength and thermal stability than films from boiling and boiling-vacuum techniques. The boiling-vacuum film presents the most compact fiber structure and the highest tensile and thermal properties. This film also shows the lowest electrical properties and the dimmest LED light. These results demonstrate the TOBCP properties from different methods that can be used to prepare film with desirable properties.
