Summary of thesis:

Bundles of polymeric materials are ubiquitous and play essential roles in biological systems, and often display remarkable mechanical properties. With the never-ending experimental advances in control and manipulation of molecular properties on the nanometric level follows an increasing demand for a theoretical description that is valid at this scale. This regime of nano-scale bundles of small numbers of molecules has not been investigated much theoretically; here chain–chain interactions, surface effects, entropy, nonlinearities, and thermal fluctuations all play important roles.

In my thesis, I present a broad exploration by molecular-dynamics simulations of single chains and bundles under external loading. Stretching and rearrangements of chains are investigated, as well as their breaking and dissolution.
