The Potentials and Applications of Cellulose Acetate in biosensor technology
The interest in cellulose and its derivatives has been exponentially increasing due to its excellent thermal stability, biocompatibility, chemical persistence and biodegradability. Among various cellulose derivatives, cellulose acetate (CA) has been applied in many applications including sensor systems, drug delivery systems, separation membrane, and tissue engineering. Recently, the electrospu...
متن کاملGrafting of Industrial Cellulose Pulp with Vinyl acetate Monomer by Ceric Ion Redox System as Initiator
The Ce/ Ce redox system was studied to initiate the grafting of idustrial cellulose pulp with vinyl acetate monomer. The parameters of the copolymerization reaction (reaction time, temperature, monomer and initiator contentration, freeness, chemical composition of the cellulose) were investigated and their effects are discussed.
متن کاملSynthesis and Characterization of Cellulose Acetate from TCF Oil Palm Empty Fruit Bunch Pulp
Cellulose acetate (CA) was successfully synthesized by the acetylation of TCF cellulose pulp from oil palm empty fruit bunches (OPEFB) at room temperature, using acetic anhydride as the acetylating agent and acetic acid as the solvent in the presence of sulfuric acid/sodium bisulfate as catalysts. Degree of substitution (DS) was controlled by the variables of acetylation time and acetic anhydri...
متن کاملThe influence of cellulose pulp and cellulose microfibers on the flexural performance of green-engineered cementitious composites
The aim of this study was to investigate the flexural behavior of engineered cementitious composites (ECCs) reinforced by cellulose pulp (CP) and cellulose microfibers (CMF). The reinforcements were obtained from chemical-mechanical treatments of Kraft paper and used in ECC mix design. Results showed that cement reinforced by CP exhibited a strain-hardening behavior in the three-point bending t...
متن کاملCellulose Acetate Nanofiltration Membranes for Cadmium Remediation
In this work, cellulose acetate (CA) nanofiltration (NF) membranes were prepared via non-solvent phase inversion technique (NIPS). Polymer concentration was varied from 22 to 25 wt% in order to study its effect on the membrane properties. The fabricated membranes were characterized in terms of morphological analysis using scanning electron microscopy (SEM), contact angle, water content, water p...
