Contactless construction of 3D non-Euclidean architecture from 2D flat geometry has recently drawn a great attention from materials communities. In particular, photothermal heating of black ink pattern method suggested facile localized contraction of shape memory polymers. However, the remaining ink patterns induce potential undesirable actuation from external stimuli. In this study, we demonstrate a facile construction of transparent 3D curvilinear structures using patterned black adhesives. Under exposure to near infrared light, temperature of the pre-stretched film is elevated at adhesive patterned areas above the glass transition temperature. After 3D shape-morphing, the adhesive patterns are simply removed to achieve transparent polymers to prevent further actuation. In this presentation, we will discuss radial and chiral pattern designs for complex 3D architectures and utilization of non-responsive flexible materials as well as conductive substance to endow multifunctionality. |
