Memory shape polymers
Web2 jul. 2024 · Shape-memory polymers (SMPs) are a kind of very important smart polymers that have multiple shape capacities. They can be deformed and subsequently fixed into a temporary shape, which would remain stable unless they are exposed to an appropriate external stimulus such as temperature, light, pH, electric or magnetic field, and specific … WebThe present work is focused on developing external stress-free two-way triple shape memory polymers (SMPs). Accordingly, a series of innovative approaches are …

This designer material has a storage modulus of ∼5.2 GPa at room temperature and ∼90 MPa in the rubbery state at 150 °C, …
WebThe material is said to demonstrate a shape memory properties since it can be deformed, fixed into a temporary shape, and recover its original shape, during exposure to an external stimulus. The shape memory property of polymer is related to the change of its elastic modulus under various conditions, however the most common activator is heat. Web28 nov. 2006 · Shape-memory polymers represent a promising class of materials that can move from one shape to another in response to a stimulus such as heat. Thus far, these systems are dual-shape materials. Here, we report a triple-shape polymer able to change from a first shape (A) to a second shape (B) and from there to a third shape (C).
