The invention discloses a reinforced heat-resistant electrostatic-
spinning /
electret composite
fiber membrane filtering material. The reinforced heat-resistant electrostatic-
spinning /
electret composite
fiber membrane filtering material is prepared from, by weight, 75-85 parts of
polyetherimide, 7-13 parts of
silicon monoxide, 10-16 parts of powdered
activated carbon, 1-2 parts of a 3-aminopropyltriethoxysilane
coupling agent, 0.8-2 parts of glacial
acetic acid, a proper amount of deionized water, 2-6 parts of
metatitanic acid, a proper quantity of a AgNO3 solution of 0.6 mol / L, a proper amount of N-methyl-pyrrolidone, 1-2 parts of oxidized
graphene, 1-3 parts of
zinc nitrate hexahydrate, 3-9 parts of dimethyl
imidazole and 25-40 parts of methyl
alcohol. According to the reinforced heat-resistant electrostatic-
spinning /
electret composite
fiber membrane filtering material,
silicon nanowires containing alpha-
quartz are prepared, the electrostatic-spinning / electret composite fiber filtering material is prepared with the
electrospinning technique, the excellent charge storage stability is achieved, and the filtering efficiency of the filtering material is greatly improved; in addition, nano-silver is added to load nanometer titania, the antibacterial durability of the filtering material is improved, and the long-
time efficient filtering effect is achieved.
