What can shape memory polymer be used for?
There are a range of potential uses for shape memory polymers for medical applications. This include less invasive, smart medical implants, tissue scaffolds and medical devices.
Is PCL a shape memory polymer?
Poly(ε-caprolactone) (PCL) is a thermoresponsive shape memory polymer (SMP) that has been explored as self-expanding stents, (1−3) self-tightening sutures, (4−6) and, recently, by our group, as self-fitting scaffolds to treat irregularly shaped bone defects.
Where are shape-memory alloys used?
Nickel-titanium (NiTi) shape-memory alloys (SMAs) have been used in the manufacture of orthodontic wires due to their shape memory properties, super-elasticity, high ductility, and resistance to corrosion. SMAs have greater strength and lower modulus of elasticity when compared with stainless steel alloys.
Is PDMS a shape memory polymer?
Programmable, reversible and repeatable wrinkling of shape memory polymer (SMP) thin films on elastomeric polydimethylsiloxane (PDMS) substrates is realized, by utilizing the heat responsive shape memory effect of SMPs.
What is an example of a shape memory alloy?
The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (NiTi), but SMAs can also be created by alloying zinc, copper, gold and iron.
Where are SMA used?
How are shape memory alloys used in real life?
They are used as wires and tubes in applications with hot fluids flowing through them. These materials are ideal as they can retain their shape even in a heated environment. Another application of SMAs is in civil engineering. For example, they have been used in bridge structures.
What are the examples of shape memory alloys?
How are shape memory alloys used in medicine?
This alloy combines the characteristics of the shape memory effect and superelasticity with excellent corrosion resistance, wear characteristics, mechanical properties and a good biocompatibility. These properties make it an ideal biological engineering material, especially in orthopaedic surgery and orthodontics.
