... Hybrid random polymers with sulfonated and phosphonated (SulPhos) segments are prepared in a single step. The hybrid polymer demonstrates conductivity both at low and high temperatures simultaneously. The sulfonated segment interconnects with the phosphonic domain at a high temperature and participates in a ‘cooperative proton conduction’ requiring no water or moisture for protons to hop. The cond ...

It is desirable but still challenging to explore CNFs with both multiscale porous structures and high heteroatom doping. Herein, hierarchically porous CNFs (HPCNFs) are prepared with the use of poly(acrylonitrile-co-acrylic acid) (P(AN-co-AA)) and terephthalic acid (PTA). The degradation of the AA ...
