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（AFM）压痕测量与光学显微镜相结合，在溶剂蒸发过程中对溶胀纤维素珠的力学性能和尺寸变化进行了原位测量。提出了三个因素来控制溶胀状态和干燥过程中纤维素珠的力学性能：（i）纤维素浓度，（ii）纤维素实体之间的相互作用，（iii）纤维素珠内网络结构的非均质性。
