Did you know?
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… WebWe proposed the “rod–coil competitive mechanism” for the self-assembly of polymer brushes with rod–coil backbones. The results indicated that the micellar structures …
