Webb19 juli 2024 · DGEBA/IAHBP showed high shape fixity ( Rf ∼ 97%) and recovery ratio ( Rr ∼ 99%) over ten shape memory cycles, which involved grasping and loosening motions and the recovery of complex objects such as flower-shaped and 3D butterfly-shaped objects. Webb18 mars 2024 · In addition, EPSis show good thermadapt shape memory behaviours (the shape retention ratio is 80.5–86.3%, the shape fixity ratio is 97.1–98.9%, and the shape recovery ratio is 95.6–99.8%), and they can convert from planar films into various shapes such as a “six-claw stool”, “wave-like rocking chair”, “windmill” and “paper ...

Webb2 mars 2015 · In this article, we report a two component epoxy-amine shape memory polymer system with tunable Tg (between 40 °C and 80 °C) and excellent shape memory properties in terms of shape fixity, shape recovery ratios, and cycling stability. Importantly, its values of strain at break above Tg and at the Tg peak reach 111% and 212%, … WebbAbstract. Due to the intrinsic properties of polymers, medical applications have been the primary targets for the development of shape memory polymers (SMPs) exhibiting … designs by bethany pequot lakes mn

Webb10 mars 2024 · With this system, we achieved good to excellent shape fixity ratios (50–90%) and excellent shape recovery ratios (∼100%, almost instantaneously) at body temperature (37 °C). Cytocompatibility tests demonstrated good viability either with cells on top or encapsulated during all shape memory processes. WebbMoreover, owing to the outstanding shape fixity ratio (R f) and shape recovery ratio (R r) of SMPU and the mechanical properties of PU foam, the rGO/SMPU/PU foam shows an excellent shape memory effect (more than 98% R f and R r … Webb29 aug. 2013 · Photoinduced shape fixity and thermal-induced shape recovery.
