Active soft materials exhibit various dynamics ranging from boat pulsation to thin membrane deformation. In the present work, in situ prepared ethanol-containing chitosan gels propel in continuous and intermittent motion. The active life of the organic material loaded to the constant fuel level follows a linear scaling, and its maximal velocity and projection area decrease steeply with chitosan concentration. A thin propelling platelet forms at low polymer content, leading to the suppression of intermittent motion. Moreover, the fast accelerating thin gels can split into a crescent and circular-like shape or fission into multiple asymmetric fragments.
活性软物质表现出各种动力学行为，从船波运动到薄膜变形。在本工作中，原位制备的含乙醇壳聚糖凝胶呈现连续和间歇运动。在恒定燃料水平下，负载的有机材料的活性寿命呈线性比例增加，其最大速度和投影面积随壳聚糖浓度的增加而急剧下降。在低聚合物含量下形成薄的推进薄片，导致间歇运动受到抑制。此外，快速加速的薄凝胶可以分裂成新月形和圆形，或者分裂成多个不对称的碎片。
