The processing of shape memory polymers (SMPs) using 3D printers has led to the emergence of 4D printing technology. The present study focused on the creation of new polymer blends that incorporate maleic anhydride grafted SEBS (SEBS-g-MA) alongside poly(butyl methacrylate-co-isobutyl methacrylate) (poly(BM-coiBM)) in diverse compositions, aimed at facilitating advancements in 4D printing technologies. In the formulation with a weight ratio of SEBS-g-MA to poly(BM-co-iBM) of 6/4 (60S-40B), a co-continuous morphology was detected. With a rising concentration of SEBS-g-MA in the polymer blends, the Tg of the poly(BM-co-iBM) phase exhibited an upward shift. Dynamic mechanical analysis results indicate that the poly(BM-co-iBM) polymer within the blends transitioned from a glassy state to a rubbery state before reaching 55 degrees C, which resulted in a pronounced reduction in the storage modulus at this temperature. On the other hand, with an increase in the amount of poly(BM-co-iBM) in the blend, there was a corresponding increase in the elastic modulus values, while the elongation at break values diminished. The results from the thermo-responsive shape memory analysis demonstrated that the 60S-40B blend provided the most favorable performance. A filament suitable for 4D printing was developed from this blend for application in fused deposition modeling printers. Employing the filament, objects produced via 4D printing were developed for applications such as lifting devices, stents, door closers, cogwheels, and robotic grippers, and their shape memory properties were evaluated.eninfo:eu-repo/semantics/closedAccessSmart polymerShape memory4D printingArticle39610.1016/j.sna.2025.1171762-s2.0-105026978012Q1WOS:001603492200005Q1
