Wang, Wu published the artcileTwo-stage reactive shape memory thiol-epoxy-acrylate system and application in 3D structure design, Quality Control of 7575-23-7, the main research area is shape memory thiol epoxy acrylate system photocuring; dynamic mech property.
Shape memory polymers (SMPs) are widely applied in actuator, aerospace, and super wetting. Besides, the specific structures of SMPs are important to achieve such performance. However, the preparation process of specific structure of SMPs to achieve certain performance are always time-consuming and costly for the high crosslinking d. exists in the resin matrix. Fortunately, two-stage reactive SMPs system can be used to prepare complex structure for the function of precise material design. To attain this goal and explore new application of SMPs, we designed a novel two-stage reactive shape memory polymer (SMP) system based on non-stoichiometric thiol, epoxy, and acrylate. In this novel system, intermediate polymer with shape memory performance can be prepared in the first thermal curing stage. With the shape memory property, the intermediate polymer can be designed to a certain structure. Then, final polymer with stable and complex shape can be further fabricated after the photo-curing in the second stage. Therefore, this novel two-stage reactive SMP system shows promising applications in 3D structure manufacturing, mold-free fabrication, and spatio-selective materials.
