In recent years, the "Kirigami" have been exploited to engineer stretchable electronics that exhibit enhanced deformability without sacrificing their mechanical and electrical properties. However, kirigami-inspired engineering is often limited to passive mechanical stretching for 3D shape morphing. To counter this problem, in this study, azobenzene-functionalized liquid crystalline polymer networks (azo-LCNs) are monolithically integrated with patterned reduced graphene oxide (rGO), called azo-LCN/rGO, to achieve on-demand shape reconfiguration in response to external stimuli (UV, NIR, solar rays, and portable light); in addition, the azo-LCN/rGO exhibit highly enhanced mechanical and electrical properties. The cross-sectional area and thickness of rGO patterns are controlled using a masking technique and evaporative self-assembly. By the spatial patterning of rGO, insulating azo-LCNs are converted into electrically conducting structures (381.9 S cm(-1)). The elastic modulus of <2 mu m thick azo-LCN can be tailored in the range of 1.3-6.4 GPa by integration with rGO layers of thickness less than 2 mu m. Upon UV irradiation, azo-LCN/rGO exhibit both for/backward in-plane bending as well as out-of-plane chiral twisting, thus overcoming the typical trade-off relationship between elastic modulus and deformability. Finally, an on-demand contactless shape reconfiguration in azo-LCN/rGO by UV irradiation in conjunction with passive mechanical strain is demonstrated.
