Intrinsic nanoscale phase separation in polymers is demonstrated experimentally and theoretically for the first time. Dense stable nanodots with size ≈80 nm have been created over large areas in polymethylmethacrylate and poly(vinylidene fluoride-trifluoroethylene) blend films, and a model is developed to show that the intrinsic nanoscale phase separation is related to the hydrogen bonding and size-dependent surface tension intimately.
