제목 Synthesis of Mesoporous Carbon derived from Polymerization-Induced Microphase Separation of Block Copolymers
초록 Mesoporous carbon has been widely used in various applications such as batteries, fuel cells, electrocatalysts and biosensors. Amphiphilic block copolymer is generally used as a structrue directing agent for porous structure to give large mesopores. Here, we suggest introducing of polymer both as a carbon source and a structure directing agent. Microphase-separated polymer nanostructure was first obtained by atom transfer radical polymerization (ATRP). Styrene and divinylbenzene were randomly polymerized under existence of PEO-Br macroinitiator. Divinylbenzene can prevent coarsening of styrene block, resulting in microphase separation of PEO block and S/DVB block. To produce mesoporous carbon, S/DVB block was hypercrosslinked using Friedel-Crafts alkylation. After further heat treatment at 700 °C, mesoporous carbon was obtained.
