- PIPERAZINIUM-MEDIATED CROSSLINKED POLYIMIDE-POLYDIMETHYLSILOXANE POLYMER AND GAS SEPARATION MEMBRANE USING THE SAME

摘要

The present invention relates to the production of polyimide (PI) -polydimethylsiloxane (PDMS) polymers and gas separation membranes crosslinked with Piperazinium, more particularly to a high permeability PDMS fraction and a PI (Particularly, CO ₂ ) by cross-linking the main chain copolymer comprising the poly (ethylene glycol) portion and the poly (ethylene oxide) portion in a predetermined composition range with the ionic liquid system salt, piperazinium, to produce a high- A polyimide-polydimethylsiloxane polymer crosslinked with piperazine, a method for producing the same, and a high performance gas separation membrane using the same.
