Document Type and Number:
WIPO Patent Application WO/2023/236490
Kind Code:
A1
Abstract:
Provided are a photocuring 4D printing method for a multilayer structure having an adjustable shape recovery speed, and a multilayer structure. The multilayer structure printed by the photocuring 4D printing method for a multilayer structure having an adjustable shape recovery speed comprises a plurality of deformation units; the plurality of deformation units are sequentially connected in series, and each of the deformation units comprises slow layers, a fast layer (3), and a transition layer (2); the fast layer (3) is disposed between two slow layers, and the transition layer (2) is disposed between at least one slow layer and the fast layer (3). A low cross-linked layer is doped with a carbon nano light-absorbing material, such that the problem that the low cross-linked layer is prone to over-curing by printing a high cross-linked layer to the low cross-linked layer is solved.
