该研究探讨了海鞘纤维素纳米纤维（Tunicate Cellulose Nanofibers, tCNFs）在皮克林乳液中的应用潜力。以海鞘被囊粉为原料，经离子液体-球磨法成功制备了tCNFs。通过透射电子显微镜、傅里叶变换红外光谱、X射线衍射和热重分析等技术对tCNFs的形貌和结构特征进行分析；再进一步制备乳液并表征乳液性质，以期评估其乳化性能。结果表明，所制备的高纵横比的丝状tCNFs具有出色的胶体稳定性、高结晶度（76.48%）和较高的热稳定性（热降解峰值温度为384.20 ℃），还具有利于乳化性能的亲疏水性。通过研究tCNFs的乳化性能，发现tCNFs在稳定十二烷时，表现出更好的乳化性能，具有最小的油滴粒径为7.39 μm。另外，油相种类、颗粒浓度（c）和油相比例（?）对tCNFs所稳定乳液性质具有可调控的影响。当c > 0.3 wt.%或? < 0.7时，乳液具有良好的稳定性且倾向于形成凝胶状乳液。综上可见，tCNFs是一种具有良好乳化性能的颗粒稳定剂。这些发现为动物源纤维素基颗粒稳定剂的开发利用提供了理论参考。

In this study, the potential application of tunicate cellulose nanofibers (tCNFs) as particle stabilizer for Pickering emulsions was explored. An efficient method for preparing tCNFs was developed using mechanical ball milling with an ionic liquid as the wet milling medium. The morphology and structural characteristics of tCNFs were examined by transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. Furthermore, to evaluate their emulsifying properties, emulsions were prepared, and their characteristics were analyzed. The results revealed that the tCNFs exhibited a silk-like structure, excellent colloidal stability，high crystallinity (76.48%), and good thermal stability (Tp = 384.20 ℃). Additionally, their hydrophobicity contributed to favorable emulsifying performance. The investigation into the emulsifying properties of tCNFs showed that the type of oil phase, particle concentration (c), and oil phase ratio (?) exerted controllable effects on the characteristics of tCNFs-stabilized emulsions. Notably, tCNFs demonstrated superior emulsifying performance when used to stabilize dodecane, achieving a minimum oil droplet size of 7.39 μm. When the particle concentration (c) exceeded 0.3 wt.% or the oil phase ratio (?) was below 0.7, the emulsion displayed enhanced stability and a tendency to form a gel-like structure. In conclusion, these findings highlight the great potential of tCNFs as effective Pickering stabilizers. These findings provide theoretical basis for the development and utilization of cellulose-based particle stabilizers derived from animal sources.
