摘要

This chapter evaluated the effects of different halloysite nanotube (HNT) content on shape memory behaviour and compressive properties of polyurethane (PU)/HNT nanocomposites manufactured via fused deposition modelling (FDM). Strip-like and re-entrant (RE) structures were manufactured in this study based on PU (MM4520 grade) and HNTs with the combination of solution casting, melt extrusion and 3D printing. Such samples were additively manufactured on the basis of optimum factor-level combination for L18 orthogonal array (OA) in response to maximum tensile strength at yield.
