| 제목 | Synthesis of biodegradable cationic cellulose nanofibrils as an alternative of conventional cationic surfactants |
| 초록 | Petrochemical cationic surfactants have shown poor biodegradability, giving rise to accumulation in the aquatic environment. This study was designed to address a novel cationic surfactant, derived from bacterial cellulose nanofibrils, with better biocompatibility. For this, bacterial cellulose (BC) was charged cationically with glycidyltrimethylammonium chloride (GTAC). To enhance amphiphilicity of amine-functionalized BC (ABC), we added 3-aminopropyltriethoxysilane (APTES) using silane-coupling reaction, following the alkylation with stearic acid. The rheological analysis confirmed that C18-ABC generated a fibrillary membrane at the O/W interface and stabilized microemulsion droplets. We also observed CLSM images to highlight the sufficient adhesion of C18-ABC to hair strands. Therefore, we substantiate that natural-based C18-ABC is estimated to have the potential to be an alternative to conventional cationic surfactants with desired interface tunability. |
