In our article, we reported on the interfacial dilatational and interfacial shear rheology (ISR) of cellulose nanocrystals (CNCs) at the air–water interface. We found that adsorbed CNC layers exhibit negligible viscoelasticity at a low ionic strength, but viscoelasticity can be increased by salt-induced charge screening due to increasing attractive particle interactions. In contrast with dilatational rheology, ISR data could only be obtained beyond a critical CNC and NaCl concentration (0.3 wt % CNC at 25 mM NaCl and 0.5 wt % CNC at 20 mM NaCl, respectively), which was attributed to the minimum detectable torque signal of the rheometer. Although CNCs were shown not to aggregate at these NaCl concentrations, we found that they enter a colloidal arrested (glassy) state that exhibits significant elastic contributions and corrupted the presented ISR data, as confirmed in a previous correction by fully immersing the ISR geometry (bicone) in the bulk.(1) Hence, the presented ISR oscillatory amplitude sweeps and corresponding Lissajous plots (Figures 5 and 6) do not represent the viscoelastic response of adsorbed CNCs but the elastic contributions of the arrested bulk phase. The presented interfacial dilatational rheology data were obtained at lower CNC and NaCl concentrations and are thus not affected by this issue (with the exception of Figure 4F). Hence, most of the conclusions drawn in the manuscript remain valid as they are supported by interfacial dilatational rheology. However, two conclusions that were drawn based entirely on ISR oscillatory amplitude sweeps may not be correct. These are, namely, the formation of CNC interfacial layers with a broad linear viscoelastic regime (i.e., high critical strain) and the presence of a yield point followed by strain thinning due to alignment in the flow field.

对“带电各向异性纤维素纳米晶体在空气-水界面的界面流变学”的更正。

在我们的文章中，我们报道了空气-水界面处的纤维素纳米晶体（CNC）的界面膨胀和界面剪切流变学（ISR）。我们发现，吸附的CNC层在低离子强度下表现出可忽略的粘弹性，但是由于增加的有吸引力的粒子相互作用，盐诱导的电荷筛选可以增加粘弹性。与膨胀流变学相反，ISR数据只能通过超出临界CNC和NaCl浓度（分别在25 mM NaCl时为0.3 wt％CNC和在20 mM NaCl时为0.5 wt％CNC）获得，这归因于最小的可检测扭矩信号流变仪的。尽管显示CNC在这些NaCl浓度下不会聚集，我们发现它们进入了胶态阻滞（玻璃态）状态，该态态表现出显着的弹性作用并破坏了所呈现的ISR数据，正如先前通过将ISR几何形状（双锥）完全浸没在主体中所证实的那样。（1）因此ISR振荡振幅扫描和相应的Lissajous图（图5和6）不代表吸附的CNC的粘弹性响应，而是代表滞留体相的弹性贡献。给出的界面膨胀流变学数据是在较低的CNC和NaCl浓度下获得的，因此不受此问题的影响（图4F除外）。因此，手稿中得出的大多数结论在界面膨胀流变学的支持下仍然有效。然而，完全基于ISR振荡幅度扫描得出的两个结论可能不正确。这就是说，形成具有宽线性粘弹性范围（即高临界应变）的CNC界面层，并存在屈服点，然后由于流场的对准而使应变变薄。本文引用了其他1个出版物。
