Density functional theory for rod-coil polymers with different size ...

In polymer chemistry, a random coil is a conformation of polymers where the monomer subunits are oriented randomly while still being bonded to adjacent units. It is not one specific shape, but a statistical distribution of shapes for all the chains in a population of macromolecules. The conformation's name is derived from the idea that, in the absence of specific, stabilizing interactions, a polymer backbone will "sample" all possible conformations randomly. Many unbran… WebRod–coil graft copolymers (also referred to as polymer brushes or molecular bottlebrushes) consist of a polymeric backbone with densely grafted side chains. 150–154 In general, … ford wdr
