Early research of shape memory polymer vascular stents

eXPRESS Polymer Letters, 2022
Shape memory polymers (SMPs) are smart materials that can alter their shape from a temporary shape to a permanent shape upon external stimuli. This unique property of SMP has shown enormous potential and breakthrough discoveries in biomedical engineering.

Multidirectional Triple-Shape-Memory Polymer by Tunable Cross-linking and Crystallization

, 2020
Medical fixing is one of the very important applications of the shape-memory polymer material, and the two important properties of the medical fixing material are that it perfectly fits the body during the fixing and easily detaches after being used.

Thermal-mechanical properties of polyurethane-clay shape memory polymer nanocomposites [PDF]

, 2010
Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is
