Bacterial Cellulose—Graphene Based Nanocomposites

Abstract

Bacterial cellulose (BC) and graphene are materials that have attracted the attention of researchers due to their outstanding properties. BC is a nanostructured 3D network of pure and highly crystalline cellulose nanofibres that can act as a host matrix for the incorporation of other nano-sized materials. Graphene features high mechanical properties, thermal and electric conductivity and specific surface area. In this paper we review the most recent studies regarding the development of novel BC-graphene nanocomposites that take advantage of the exceptional properties of BC and graphene. The most important applications of these novel BC-graphene nanocomposites include the development of novel electric conductive materials and energy storage devices, the preparation of aerogels and membranes with very high specific area as sorbent materials for the removal of oil and metal ions from water and a variety of biomedical applications, such as tissue engineering and drug delivery. The main properties of these BC-graphene nanocomposites associated with these applications, such as electric conductivity, biocompatibility and specific surface area, are systematically presented together with the processing routes used to fabricate such nanocomposites.

Comparative Analysis of Bacterial Cellulose Membranes Synthesized by Chosen Komagataeibacter Strains and Their Application Potential

“…Ultimately, all properties of this biopolymer strongly depend on several factors, including the pH and chemical composition of the growth medium, cultivation time, and operational conditions, as well as selection of an efficiently growing bacterial strain [ 4 ]. The relatively huge diversity of cellulose producing microorganisms, as well as the wide variety of cultivation methods (culture media and their supplementation), create a great opportunity to modify and adjust the properties of this bioinspired material and to find new applications for its usage, such as in the medical sector (wound dressings, implants, scaffolds, drug delivery devices), the field of electronics (sensors, energy storage devices, speakers, acoustic membranes, OLEDs), the environmental sector (water treatment, filtration and adsorption techniques), paper engineering, and the food industry (artificial food, additives, food packaging) [ 3 , 5 , 6 , 7 , 8 , 9 , 10 ].…”

Bacterial Cellulose Properties Fulfilling Requirements for a Biomaterial of Choice in Reconstructive Surgery and Wound Healing

“…In this field, the challenge is in functionalizing cellulose in such a way as to make it an actual release system. Hence, new, non-aggressive methods of increasing cellulose reactivity (e.g., enzymatic oxidation) or the development of composites, e.g., with magnetic, thermo-and photosensitive properties, (Ivanova et al, 2020;Kim et al, 2020;Troncoso and Torres, 2020;Poddar and Dikshit, 2021;Sriplai and Pinitsoontorn, 2021). This direction of research may lead to developing a carrier that will be non-toxic, functional and adapted to the state-of-the-art treatment methods.…”

Bacterial Nanocellulose toward Green Cosmetics: Recent Progresses and Challenges

“…Irrespective of its source, it is a linear polysaccharide of β- d -glucopyranose units linked by β-1,4-glycosidic bonds [ 16 ]. Although plant cellulose is the most used cellulose substrate, bacterial nanocellulose (BNC, also known as microbial cellulose, bacterial cellulose or biocellulose), is currently regarded as a promising cellulose form for a wide range of applications, including in cosmetic [ 17 , 18 ], food [ 18 , 19 , 20 ], pharmaceutical and biomedical [ 21 , 22 , 23 , 24 , 25 , 26 ], and technological fields [ 27 , 28 , 29 , 30 ].…”
