Abstract

Bacterial cellulose and eggshell composite was successfully developed. Eggshell was mixed with bacterial cellulose suspension and it was casted as a composite film. CaCO3derived from eggshell was compared with its commercial availability. It can be noted that good dispersion of eggshell particle was prepared. Eggshell particle was irregular in shape with a variation in size. It existed in bacterial cellulose network. Characterization on composite was focused on thermal and mechanical properties. It showed that flexibility and thermal stability of composite were enhanced. No significant effect of mechanical properties was therefore observed. The thermal stability of composite was stable up to 300°C. The adsorption experiment on water and vegetable oil capacity was performed. The enhancement on adsorption was due to the existence of eggshell in bacterial cellulose composite. It exhibited the potential to be a good candidate for absorbent material in active packaging.

Highlights

In recent years, the push on development on bio-based materials has been evident
The role of bio-based materials can be employed in many sectors of application such as infrastructure, automotive part, and electronic device as well as active packaging [4,5,6]
One successful project was involved in the development of bacterial cellulose as a flexible substrate for electronic device

Summary

Introduction

The push on development on bio-based materials has been evident. Numerous efforts have been extensively developed in many types of bio-based products such as cellulose and derivatives, chitin and chitosan based materials, polylactic acid, polybutylene succinate, and starch as well as soy protein [1,2,3]. From the fundamental point of view, it was remarkable to note that cellulose was considered as the most abundant naturally occurring biopolymer It was commonly found in the cell walls of plant and certain algae. The most effective specie was focused on Acetobacter xylinum It presented the low coefficient of thermal expansion and it was an outstanding reinforcing agent for the design of environmentally friendly composites. Bacterial cellulose composite presents the flexibility and transparency and it gains many interests in the further development in electronic industries such as flexible device, the use of bacterial cellulose based materials provided high water absorption ability. Due to the high absorption ability of bacterial cellulose, the development of bacterial cellulose as absorbent materials has been
