4D打印电响应展开结构及水下减速性能
4D printing electrical response deployment structure and underwater deceleration performance
摘要
Abstract
The electrically driven unfolding structure with efficient thermally/electrically triggered shape memory effect was prepared by reserving conductive path in the polyurethane acrylic printing matrix and spraying graphene conductive solution.The electrically responsive shape memory behaviors of the structure were tested at room temperature and underwater environments.The results show that the unfolded structure can quickly respond and recover under low voltage conditions in different environments.The prepared electrically driven structure has excellent shape recovery function in underwater environment,and the shape changes of different surface structures under electrical stimulation have significant deceleration effect on the underwater vehicle.This study provides new ideas for the application of 4D printing in underwater intelligent actuators and electronic devices.关键词
