polyethersulfone copolymer of Intrinsic Microporosity, preparation of method and membrain for gas separation using the same

摘要

The present invention is a polyether sulfone copolymer having an intrinsic micro- porosity , its preparation method and using the same gas relates to a separation membrane , a gas separation membrane is produced , including a polyether sulfone copolymer having micropores according to the invention has got the pores of the nano- size, high surface area , as well as nitrogen gas (N ₂ ) and facilitates the permeation of low molecular weight gases, such as , since the high thermal stability due to the skeletal shape of a ladder , electron gas separation membrane is used which material , pharmaceutical manufacturing , food packaging , protective equipment , fuel cells , a variety of fields , such as integers may be useful for . ;
