摘要
形状记忆聚合物(SMPs)是一种智能材料,近年来因其在智能结构和设备中的广泛应用而备受关注。数字光处理(DLP)是一种基于大桶光聚合的技术,是一种可在一个步骤中打印完整层的快速技术。本研究报告了一种使用 DLP 3D 打印机和定制树脂轻松快速地 3D 打印基于 SMP 的智能结构的方法。液晶(LC,RM257)与树脂的结合引入了形状记忆特性。液晶与光固化树脂的结合为直接三维打印热致伸缩结构提供了机会,避免了 SMP 树脂制备的复杂性。打印出的结构具有不同的几何形状,并对形状记忆响应进行了测量。通过制造和编程晶格结构,获得了可调的机械性能。此外,还测量了应变传感响应,以证明这些晶格结构可用作关节运动传感的智能贴片。智能贴片的制备非常方便,可用于智能工具、玩具和超材料传感器等多种应用。
Swift 4D printing of thermoresponsive shape-memory polymers using vat photopolymerization
Shape-memory polymers (SMPs) are smart materials that have gained significant attention in recent years owing to their widespread application in smart structures and devices. Digital light processing (DLP), a vat-photopolymerization-based technique, is a significantly faster technology for printing a complete layer in a single step. The current study reports a facile and fast method for the 3D printing of SMP-based smart structures using a DLP 3D printer and a customized resin. A liquid crystal (LC, RM257) was combined with the resin to introduce shape-memory properties. The combination of LCs in photocurable resin provides the opportunity to directly 3D-print thermoresponsive structures, avoiding the complexity of SMP resin preparation. The structures were printed with different geometries, and the shape-memory response was measured. Lattice structures were fabricated and programmed to obtain tunable mechanical properties. Furthermore, the strain-sensing response was measured to demonstrate the utility of these lattice structures as smart patches for joint-movement sensing. The SMPs can be prepared conveniently and can potentially be used for various applications, such as smart tools, toys, and meta-material sensors.
