This study introduces novel method for stabilizing high internal phase emulsion (HIPE) with biocompatible cellulose surfactant. Herein, we synthesized alkylchains-grafted diimine bacteria cellulose nanofibers (C18-DIBC) that not only enhance emulsion stability but also show high rheological properties. For this, we synthesized dialdehyde cellulose (DAC) from TEMPO oxidized bacterial cellulose (TOBC) with oxidant, sodium periodate. To give amphiphilicity to DAC, we grafted octadecylamine using Schiff’s base reaction. The wettability of C18-DIBC was adjusted by controlling the contents of alkylchains. From rheological analysis, we observed that C18-DIBC highly enhanced the membrane modulus compared to DAC. Finally, HIPE was successfully stabilized by the resilient interfacial membrane. From these findings, we demonstrated that adsorbed C18-DIBC played a key role in structural stability of HIPE. |
