| Abstract Scope |
Shape memory polymers are structurally active polymers that find application in advanced research fields such as robotic sensors, medical devices, and actuators. However, these materials usually lack structural properties or are only processable via complex cleanroom technologies, restricting their scope of applications. In this work, we utilized an FFF 3D printer for processing in-house developed smart polymer systems and fabricating structures for application in tactile robotics and 4D structures. We developed highly stretchable (> 600%) filaments for a novel shape memory polymer composite and tested their 3D printed parts for the mechanical properties and shape recovery behavior. Additionally, the effect of adding fillers such as carbon fiber and graphene on composite rheology and mechanical properties was analyzed. Furthermore, dynamic mechanical analysis (DMA) was conducted for all the compositions to quantify the shape memory characteristics. Finally, the extent and rate of recovery were also analyzed using the high-speed video capture method. |
