Imagine a robotic arm that doesn't need a mechanism to move. or surgical instruments that can enlarge or reshape the inside of the body Although it may sound strange and wonderful. But it actually exists.These bizarre tools all rely on shape memory polymers. Now, Stanford researchers have created a shape memory polymer that is stronger and more
capable than any
slot other model. that had previously They published their results last week in the journal ACS Central Science.Shayla Nikzad, a graduate student at Stanford University and one of the study's lead authors, said: “[Shape-memory polymers] have been used commercially in our lives for quite some time.
Polymers are very long molecules. It is made up of many small molecules linked together in giant chains. It is not an exaggeration to think that polymers drive our world. The DNA behind your cells is a polymer. Silk and gelatin are also made from polymers. in your daily life You often come up with the man-made polymers that make up plastic and synthetic rubber.
Shape memory polymers are a special type of polymer. when you bend them The molecules in the polymer form some special bonds. And when you're exposed to stimuli like light, electricity, or temperature changes, most of the time, these bonds break and hold the polymer back up.in other words Shape memory polymers "remember" their original shape. and able to transform
himself back into his true form Many engineers find the capability to be irresistible.Kai James, professor of aerospace engineering at the University of Illinois. Urbana-Champaign which is not the writer said "So we can use shape memory polymers to create devices ... that change shape without having to pull or stretch on paper.
