A multi-performance MWCNT-reinforced chitosan nanocomposite was fabricated by unique methods: a freeze-drying process associated with the sublimation and compression (SAC) method, and the casting-evaporation (CE) method. We obtained ordered and multilayered structures with limited porosity, and well-dispersed MWCNT structures of the chitosan nanocomposite, especially when the SAC method was used. In the case of films prepared byCE method, the mechanical strength and elongation were significantly increased by up to about 40% compared with the pure chitosan films. On the other hand, the ordered and porous multilayered pure chitosan films prepared by the SAC method showed significantly lower tensile strength and elongation compared to the pure solid chitosan films. |
