Abstract

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.

用酯化纤维素纳米纤维稳定的皮克林乳液的特性和稳定性
利用纤维素纳米纤维(CNFs)和十二烯基琥珀酸酐(DDSA)制备了改性纤维素纳米纤维(D-CNFs)。D-CNFs 具有部分可润湿性,可用作理想的皮克林乳液稳定剂。此外,D-CNFs 在乳液中的稳定性优于 CNFs。当 D-CNFs 的浓度增加到 3.0wt% 时,乳液的流动性明显降低。通常情况下,当 D-CNF 的浓度为 1.2wt% 时,性能最佳。与低 pH 值相比,乳液在碱性环境中更为稳定。由于添加了离子,乳液的液滴尺寸明显增大。然而,就宏观稳定性(CI)而言,当 NaCl 浓度不高于 50mM 时,乳液可保持 7 天不分层。结果表明,D-CNFs 可用于制备 Pickering 乳液,具有良好的发展前景。

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.
