They can regain their original shape when heated. They are often used for car bodies. If the car gets dented its surface can be heated (e.g. with a hair dryer) and the shape memory polymer should regain its original shape

Some amazing applications are security label and multi-pede chair.
Shape memory label film is made from shape memory polymer by extruder machine, the security information of covert embossed pattern is stored in the label film internally, heating the label film, security information will be released in just seconds irreversibly.
Shape memory label film can be used as label substrates or face stock for security label, brand protection, tamper-evident seals, anti-pilferage seals, etc.

How do designer polymers work?
They have more useful properies than other polymers
How do stitches made from smart polymers work?
When a shape memory polymer is used to stitch a wound loosely, the temperature of the body makes the thread tighten and close the wound, applying just the right amount of force. This is an example of a 'smart' polymer. i.e. one that changes in response to changes around it. In this case a change in temperature causes the polymer to change its shape. Later, after the wound is healed, the material is designed to dissolve and is harmlessly absorbed by the body. Hope this helps:)
Why do natural polymers not pose as much of an issue in landfills as synthetic polymers Natural polymers are cheap to recycle and synthetic polymers are expensive to recycle. Natural polymers are expe?
Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
What arethe advantages and disadvantages of shape memory alloys?
The advantages are they will remember the shape that you want. The disadvantages is that they will be hard to change.
When monomers combine they form what?
Monomers hook up to form polymers. There is a link below that will lead you to the Wikipedia post on polymers.Water is also produced, this is a condensation reaction.
What has the author Andreas Lendlein written?
Andreas Lendlein has written: 'Shape-memory polymers' -- subject(s): Polymerization, Shape memory effect, Biocompatible Materials, Smart materials, Polymers, Chemistry, Polymeric composites
What is smart material made from?
There are lots of smart materials.For example,Shape memory alloys are made from metal alloysShape memory polymers, which are plasticsEtc
What is a neat polymer?
A new and usefull polymer is new polymers that are developed to help society- for example shape memory polymers are used to cure cuts.When a shape memory polymer is used to stitch a wound your body tempreture makes it tighter and close around the wound.This is just one example of a new polmer which is usefull. Hope i helped.
What is a plastic bumper?
in old cars bumpers was made of steels and other heavy metal materials nowadays polymer composites are use in this field because of their Strength and Lightness TPOs( thermoplastic olefins) are good example for this case at the other hand, the importance of polymers is their "memory effect" we can call this effect "the polymers Secret of success" polymers have memory like a Spring after an accident, when the impact makes bumpers deformed, the plastic bumpers can return to their previous shape memory effect and lightness is just two of the benefits that will convinced us to Farewell with metal bumpers

How does memory metal work?
A shape memory alloy (SMA, smart metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original, cold, forged shape, and which returns to that shape after being deformed by applying heat. This material is a lightweight, solid state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape memory alloys have applications in industries including medical and aerospace.
What is Shape memory effect?
the change of shape of a metal at low temperature by loading and regaining of original shape by heating it,is known as shape memory effect

What does a magic memory stick do?
holds a shape
What is the metal with a memory?
There are several alloys that exhibit shape memory, the most widely known is Nitinol.
Which memory card will work best with my Ipod?
The ipod does not have a memory card slot, so no memory card will work with it.
What does SMA stand for?
In science if you are talking about smart materials SMA stands for 'Shape memory Alloy' Also SMP stands for 'Shape Memory plastic'
