▎ 摘  要

Irreversible covalent network in thermosets brings great difficulty to their reprocessing. Especially, customizing devices with sophisticated architecture still remains a challenge. Herein, a novel "paper art" strategy is developed for preparing epoxy-based components or devices with specifically designed structure by introducing dynamic Diels-Alder network and well dispersed Graphene in epoxy matrix. The physical or chemical transitions such as glass transition, reversible dissociation/reconstruction and irreversible dissociation of DA network are spatially and temporally controlled by NIR-triggered in-situ photothermal conversion of GE and therefore served as "folding", "bonding" and "scissoring", which are three fundamental operations of "paper art", respectively. Thus, by setting up the program of these NIR light-manipulated fundamental operations, epoxy resin composite-based devices with designed hierarchical architecture are facilely prepared.
