Current progress in production of biopolymeric materials based on cellulose, cellulose nanofibers, and cellulose derivatives

Cellulose-based materials

Cellulose represents the most abundant renewable and biodegradable polymeric material on earth. Due to its low cost and functional versatility, cellulose has been a key feedstock for the production of chemicals with various properties and applications over the past century. In 2000, the world produces 187 million tons of wood pulp annually. Most of it is used as raw material in the production o...

Application of Cellulose and Cellulose Derivatives in Pharmaceutical Industries

Nanofibers of cellulose and its derivatives fabricated using direct electrospinning.

A short review with 49 references describes the electrospinninng (ES) process for polysaccharides, cellulose and chitosan, and their derivatives, including cellulose acetate and hydroxypropyl cellulose. A majority of applied studies adopted a two step-process, in which the cellulose acetate was used for the first ES process, followed by acetyl group removal to regenerate cellulose thin fibers. ...

Size Exclusion Chromatography of Cellulose and Cellulose Derivatives

Approximately 2 X 10 ton biomass is produced on land and in water annually (l). Cellulose is the principal structural material in the cell wall of all plants (2). In addition, cellulose can be found in algae, bacteria, and animals (tunicates). Assuming that the average source contains 50% cellulose (Table 1) (35), then approximately 1 X 10 ton cellulose is formed each year. This makes cellulose...

Antibacterial Activity and Conductivity Properties of Nanocomposites based on Cellulose Acetate Nanofibers and Copper Nanoparticles

in this work, nanocomposites comprising copper nanoparticle in cellulose acetate (CA)matrices have been prepared. In this manner, Copper nanoparticles prepared by its saltreduced by sodium borohydride at various concentration. Then this nanoparticle solution wasmixed with polymer solution and electrospun by electrospinning device. The abovenanocomposite has been successfully detected by SEM, ED...
