Nanocelluloses in recent years have garnered a lot of attention for their use as stabilizers of liquid-liquid and gas-liquid interfaces. Both cellulose nanocrystals (CNCs) and cellulose nanofibers (CNFs) have been used extensively in multiple studies to prepare emulsions and foams. However, there is limited literature available that systematically discusses the mechanisms that affect the ability of nanocelluloses (modified and unmodified) to stabilize different types of interfaces. This review briefly discusses key factors that affect the stability of Pickering emulsions and foams and provides a detailed and systematic analysis of the current state knowledge on factors affecting the stabilization of liquid-liquid and gas-liquid interfaces by nanocelluloses. The review also discusses the effect of nanocellulose surface modifications on mechanisms driving the Pickering stabilization of these interfaces.
近年来，纳米纤维素因其作为液-液和气-液界面稳定剂的用途而受到广泛关注。纤维素纳米晶体 (CNC) 和纤维素纳米纤维 (CNF) 已在多项研究中广泛用于制备乳液和泡沫。然而，目前可用的文献有限，系统地讨论了影响纳米纤维素（改性和未改性）稳定不同类型界面的能力的机制。本综述简要讨论了影响 Pickering 乳液和泡沫稳定性的关键因素，并对影响纳米纤维素稳定液-液和气-液界面的因素的现有知识进行了详细和系统的分析。该综述还讨论了纳米纤维素表面改性对驱动这些界面 Pickering 稳定的机制的影响。
