Sulfoethylated nanofibrillated cellulose (NFC) was produced by an industrially relevant process. The properties of the NFC were compared with those of carboxymethylated nanofibrillated cellulose (NFC), which has been identified as an attractive NFC for several industrial applications. The investigations revealed that NFC is characterized by a higher degree of fibrillation and has superior redispersion properties. Furthermore, NFC displays higher stability in varying pH values as compared to NFC. Hence, NFC may be a more attractive alternative than NFC in applications such as rheological modifiers or adsorbing components in personal care products, in which the performance of NFC must remain unaffected in varying ambient conditions. The superior properties of NFC compared to NFC were proposed to be due to the combination of the unique chemical characteristics of the sulfoethylated reagent, and the larger size of the sulfonate group compared to the carboxymethyl group.
磺乙基化纳米原纤纤维素 (NFC) 是通过一种工业相关的工艺生产的。将 NFC 的性质与已被确定为几种工业应用中具有吸引力的 NFC 的羧甲基化纳米原纤纤维素 (NFC) 的性质进行了比较。研究表明，NFC 的纤维化程度更高，具有更好的再分散性能。此外，与 NFC 相比，NFC 在不同 pH 值下显示出更高的稳定性。因此，在流变改性剂或个人护理产品中的吸附成分等应用中，NFC 可能比 NFC 更具吸引力，在这些应用中，NFC 的性能必须在不同的环境条件下保持不受影响。与 NFC 相比，NFC 具有更好的性能，这被认为是由于磺乙基化试剂的独特化学特性以及磺酸盐基团与羧甲基基团相比的更大尺寸的组合所致。
