It was thought that stable nanostructures did not exist in the phase separation behaviors of polymers. Now it is demonstrated that strongly correlated chains induced by hydrogen bonding can lead to a new self-assembly: intrinsic nanoscale phase separation. High-density nanorings, nanodiscs and nanospheres exist over large areas in the self-assembly of polymethylmethacrylate and poly(vinylidene fluoride-trifluoroethylene) blend films. Their typical size changes from 100 nm to 20 nm, depending on substrate effect and film thickness. The phenomenon that controllable nanoscale self-assembly exists in miscible polymer blends is beyond the conventional understanding of the phase separation behavior. This may open a new way in the design of nanostructured polymers and multifunctional polymers.
