What is the difference between kuhn and persistance length?

Expert Solution
Step 1

Kuhn length is a theoretical concept in which the chain of polymer is consists of number of Kuhn segments and the length of each segment is called as Kuhn length denoted by b . Each segment joints freely with each such that it can orient in any direction without any external force.

The expression of Kuhn length is given by,
