| 제목 | Properties of cellulose nanofibers from various natural sources and preparation techniques |
| 초록 | Cellulose is the most abundant biopolymer on earth and is found in the cell walls of green plants, cotton, some marine animals, also some bacteria. Cellulose nanofibers (CNFs) are generally produced by mechanical treatment or chemical treatment, such as ultra-sonication, acid hydrolysis, TEMPO-oxidation, and enzymatic hydrolysis. These nanofibers show different properties as well as morphological shapes depending on their original raw sources and treatment methods. Therefore, we prepared CNF films by changing their sources and separation techniques. Morphology and light transmittance of the film were observed by a field emission scanning electron microscope (FE-SEM) and a UV-vis spectrophotometer. Mechanical performances of the samples were measured by a tensile testing. The crystallinities of the CNFs were determined by X-ray diffractometer (XRD). |
