New polymer blends of polyacrylonitrile (PAN) and resorcinol-based phthalonitrile prepolymer (pPN) are studied as superior carbon precursors. pPN has a hyperbranch-like structure with multiple terminal nitrile groups available for chemical interactions. The addition of pPN into PAN significantly low...
