Currently, many studies using natural polymers (bio-mass) are in progress to replace microplastics, which are causing serious environmental problems. Among them, cellulose is the most abundant natural polymer on earth and is known as one of the suitable materials to replace plastic materials since it is not-toxic, human-compatible, and biodegradable. However, natural cellulose has a limitation that it is not easily dissolved in general organic solvents due to the presence of crystalline regions and hydrogen bonds between cellulose chains. One of the cellulose derivatives, carboxymethyl cellulose (CMC), has strong anionic and hydrophilic properties and is easily soluble in water. In this study, we tried to produce CMC microbeads with a narrow particle size distribution. CMC was dissolved in water and microbeads were formed using microfluidic channel technology. We will discuss the effect of syringe needle diameter on the particle size distribution of CMC beads, when manufacturing CMC beads using microfluidic channel technology.
