Characterization and stability of Pickering emulsions stabilized with esterified cellulose nanofibrils
Cellulose nanofibrils (CNFs) and dodecenyl succinic anhydride (DDSA) were used to prepare modified cellulose nanofibrils (D-CNFs). D-CNFs are partially wettable and can be used as ideal Pickering emulsion stabilizers. Moreover, the stability of D-CNFs in emulsion is better than that of CNFs. When the concentration of D-CNFs increased to 3.0wt%, the fluidity of the emulsion decreased significantly. Typically, the best performance was exhibited when D-CNFs were added at a concentration of 1.2wt%. Emulsions were more stable in alkaline environments when compared to low pH values. The droplet size of the emulsions increased significantly due to the addition of ions. However, in terms of macroscopic stability (CI), the emulsions could remain without delamination for 7 days when the NaCl concentration is not higher than 50mM. The results showed that D-CNFs can be used to prepare Pickering emulsions and have a good development prospect.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
