What is it about?
When the polymer is stretched, the chemical bonds break with the formation of electrons and positive ions, followed by their thermal emission. Negative ions can formed due to the capture of electrons by neutral fragments of macromolecules.

Why is it important?
This phenomenon is of great importance, both for strength physics, and for the development of various sensors of physical fields. In addition, mechanical emission can interfere with the operation of flexible micro-and nanoelectronic devices and cause discharges on the spacecraft in outer space.
Perspectives
In the future, it is necessary to determine the ions. How it relates to the nature of the polymer. Understand how the polymer breaks down. Learn to manage this phenomenon.
