Nonwoven fabric of co-polymeric imide nanofiber, process of its preparation and use

摘要

monomer pyromellitic tetrakarboxylovu00e9 acid and diaminovu00fd monomer are subjected to polykondenzaci in reakcnu00edm environment with highly polar rozpoustedlem by mechanical agitation to produce a solution kopolymernthe amidkarboxylovu00e9 acid; solution amidkarboxylovu00e9 co polymeric acid is electrostatically zvlu00e1knovu00e1n in the electric field of high tension for the emergence of non wovens of nanovlu00e1kna of co polymeric amidkarboxylovu00e9 acid; and then the non-woven fabric imidizuje.non-woven fabric of kopolymernu00edho imidovu00e9ho nanovlu00e1kna has characteristics such as high resistance to roztrzenu00ed, high porosity.resistance to high and low temperatures and excellent mechanical properties, etc., and can be use in battery membru00e1ne and condenser membru00e1ne.
