【 摘 要 】

The nanofibrillated celluloses (NFC) from different sources (i.e. bacterial cellulose (BC), pineapple leaf (PA) and banana pseudostem (BA)) were prepared using microfluidization. TEM and XRD results revealed diverse characteristics of the NFCs from different sources. Then, 0.1wt% of the prepared NFCs were integrated into the bagasse (BG) paper sheets. SEM images showed the densest surface of BG/NFC-BA sheet which also exhibited the highest sheet rigidity. Furthermore, the tensile tests indicated that the BG sheet reinforced with NFC-BC, possessing the highest fiber aspect ratio (L/D of 336) and crystallinity (80%), offered the highest strength and toughness. All tensile properties of the BG sheets were impressively enhanced with very low content (0.1wt%) of NFC addition. This confirmed that NFC is a highly effective reinforcement and suitable for use in paper making industry. However, suitable sources of NFCs for a particular paper product or application should be considered in advance.
