摘要

研究了添加Tween80后聚乙烯醇(PVA)/短碳纤维(SCFs)电活性形状记忆复合材料的性能。结果表明:Tween80的加入使复合材料的电导率降低，并且随着Tween80含量的增加，复合材料的电导率逐渐降低。Tween80的加入显著改善了SCFs在基体中的沉积，对复合材料的均匀性有一定影响。当Tween80添加量为4%时，拉伸强度最佳。在导电条件下，复合材料仍表现出良好的形状恢复性能，但形状固定比有所降低。此外，还设计了一种能在电刺激下实现抓取动作的智能抓取器。上述结果表明，适当的Tween80含量的PVA/SCFs复合材料在软夹持器领域具有更大的应用潜力。

Study on the Effect of Tween80 on the Properties of PVA/SCFs Composites

The properties of polyvinyl alcohol (PVA)/short carbon fibers (SCFs) electroactive shape memory composites after the addition of Tween80 were studied. The results showed that the addition of Tween80 caused a decrease in the electrical conductivity of the composites, and the conductivity of the composites decreased gradually with the increase of the Tween80 content. The addition of Tween80 significantly improved the deposition of SCFs in the matrix, which had a certain effect on the homogeneity of the composites. When the addition of Tween80 was 4%, it had the best tensile strength. The composite still showed good shape recovery properties under conductive conditions, while the shape fixity ratio has decreased. In addition, a smart gripper which could realize grasping action under electric stimulation was designed. The above results indicated that PVA/SCFs composites with appropriate Tween80 content could provide greater possibility for the potential application in the field of soft grippers.
