Supercritical Carbon Dioxide(SCCO2)-Mediated Intercalative Polymerization of Conducting Polyaniline-Fluorinated Montmorillonite(PANI-FMMT)
Many investigators have demonstrated the feasibility of polymerization in SCCO2, but SCCO2 is always employed as “alternative” or “green” solvent，instead of “effective” medium. In fact, SCCO2 offers mass transfer property advantages over&...

HCAII-inspired Catalysts for Making Carbon Dioxide-based Copolymers: The Role of Metal-hydroxide Bond
The general characteristics of the active center of the catalysts (including zinc-cobalt(III) double metal cyanide complex [Zn-Co(III) DMCC]) for the copolymerization reaction of carbon dioxide (CO2) with epoxide are summarized. By comparing the active center, catalytic performance of the Zn-Co(III) DMCC (and other catalysts) with HCAII enzyme in the organism for activating CO2 (COS and CS2), we...
