The pristine and acetylated cellulose nanocrystal (CNC) particles were incorporated with poly(ε-caprolactone) to prepare two kinds of green nanocomposite systems: the former is incompatible, while the latter compatible thermodynamically. A rheological study was then performed systematically with various flow fields, including linear and nonlinear dynamic shear flow, creep and start-up flow. Some interesting results were shown then. The pristine CNC filled system shows far lower percolation threshold than the acetylated CNC filled one because the improved phase affinity yields diluent effect. The formation and rebuild-up of percolated network is driven by the Brownian motion of particles, which are nearly independent of altered phase affinity. However, the improved phase affinity makes the system more sensitive to the strain-responded deformation, leading to the reinforced Maxwell spring unit during creep and to a weak strain overshoot during dynamic flow. The structural evolution and relaxations of two systems were further evaluated from different perspectives.

将原始的和乙酰化的纤维素纳米晶体（CNC）颗粒与聚（ε-己内酯）掺入，以制备两种绿色纳米复合系统：前者不相容，而后者在热力学上相容。然后系统地对各种流场进行了流变学研究，包括线性和非线性动态剪切流，蠕变和启动流。然后显示了一些有趣的结果。原始的CNC填充系统显示的渗透阈值远远低于乙酰化的CNC填充系统，因为改进的相亲合力可产生稀释效果。渗透网络的形成和重建是由粒子的布朗运动驱动的，而布朗运动几乎与相亲和力的改变无关。但是，改善的相亲合力使系统对应变响应形变更加敏感，导致蠕变时增强的麦克斯韦弹簧单元，而动态流动时导致较弱的应变超调。从不同的角度进一步评估了两个系统的结构演化和松弛。
