WebJan 1, 2014 · Shape memory effect in polymers is normally achieved by relaxation of the polymeric chains due to changes in temperature. When the programming and recovery stages in the shape memory effect are produced by changes in temperature, it is said that the effect is thermally induced. In general, SMPs are formed by two active phases. WebShape-memory behavior in polymers describes the ability to store a programmed shape indefinitely and fully recover to an original shape in response to an environmental trigger. The materials are attractive for medical applications because they can be designed for biocompatibility, biodegradability, and controlled drug delivery. jessica victoria kimmichWeb15 hours ago · Multi-walled carbon nanotubes (MWCNTs) are added to the intermediate layer (Fast Layer, FL) of multilayer shape memory polymers (SMPs) to reduce curing degree and absorb overexposure.
