The mechanical properties as well as the size changes of swollen cellulose beads were measured in situ during solvent evaporation by atomic force microscopy (AFM) indentation measurement combined with optical microscopy. Three factors are proposed to govern the mechanical properties of the cellulose beads in the swollen state and during drying: (i) the cellulose concentration, (ii) the interaction between the cellulose entities, (iii) the heterogeneity of the network structure within the cellulose beads.

通过原子力显微镜研究了干燥过程中再生纤维素珠的机械性能的发展。

通过原子力显微镜（AFM）压痕测量与光学显微镜相结合，在溶剂蒸发过程中就地测量了溶胀纤维素珠的机械性能以及尺寸变化。提出了三个因素来控制处于溶胀状态和干燥过程中的纤维素珠的机械性能：（i）纤维素浓度，（ii）纤维素实体之间的相互作用，（iii）纤维素内网状结构的异质性珠子。
