WebThe statistical mechanics of a concatenated polymer chain 5133 If the topological of the concatenated chain is preserved by the adopted procedure then it will be expected to behave like a re-scaled Gaussian chain. In particular it should show elastic properties if the two end loops of the concatenated chain are held a fixed distance apart. This WebJan 18, 2024 · The worm-like chain model is a simple continuum model for the statistical mechanics of a flexible polymer subject to an external force. We offer a tutorial introduction to it using three approaches. First, we use a mesoscopic view, treating a long polymer (in two dimensions) as though it were made of many groups of correlated links or “clinks ...

However, a common approach for the statistical mechanics of polymer chains, the Gaussian chain approximation, misses key physics. By considering the nonlinearities of the problem, we …
WebRubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to …
