Nanocellulose (NC) is known to exhibit high performance in strength, modulus, lightness, thermal stability, and optical transparency. It has thus attracted great attention from industry and academia because of its potential applications such as composites, electronics, sensors, papers, coatings, films, aerogels, health care, etc. In this study, to improve thermal and mechanical properties of nanocellulose-based films, a series of films with a thickness of ~29 ㎛ are fabricated by using a casting technique of aqueous solutions including NC and polyacrylamide (PAM). The presence of specific interactions between NC and PAM in the composite films is characterized by using FT-IR spectroscopy. The macro- and microscopic structural features of the films are examined by using SEM and X-ray diffraction, respectively. The thermal stability and mechanical properties of the nanocellulose films with different PAM contents are investigated by using TGA and DMTA, respectively. |
