Cellulose Nanofiber (CNF) was fabricated using a conventional mill suspended in aqueous solution. The duration of the milling process for CNF fabrication was varied from 15 mins to 10 hours. The concentration of all CNF aqueous solutions were 1wt% and they were thermally, rheologically and morphologically characterized by means of TGA, rheometer and SEM, respectively. The aqueous CNF solutions were solvent casted into films to evaluate the physical properties. Tensile tests were conducted on CNF film strips using a UTM and surface of films were characterized by a SEM. Obvious change in rheological properties were observed as milling process duration increased, along with the decrease in mechanical strengths. |
