Abstract Scope |
Shape memory polymers can be combined with additive manufacturing to enable what is referred to as “4D Printing.” High entropy materials have garnered much attention in materials science due to the manifestation of unexpected results in terms of physical properties and phase composition. The work presented here explores the additive manufacturing of high entropy polymer blends with shape memory properties. We will present our strategy of incrementally increasing the constituents of multi-component polymer blends as a pathway towards the creation of high entropy blends. For this work we melt compounded blends of different types of linear polyesters such as thermoplastic urethane (TPU), polylactic acid (PLA), and polycaprolactone (PCL). The effect of the fused filament fabrication (FFF) process on the phase morphology and overall microstructure was determined by way of scanning transmission electron microscopy (STEM). A comparison of shape memory performance between binary and high entropy polymer blends is also presented. |
