FILTER MATERIAL FOR FINE PURIFICATION OF GASES AND PRODUCTION METHOD

摘要

FIELD: chemistry. ^ SUBSTANCE: disclosed is filter material which contains polysulphone microfibre with diameter 5-10 mcm and polydiphenylene phthalide nanofibre with diameter 300-500 nm with weight ratio of polydiphenylene phthalide fibre to polysulphone fibre equal to 1:(5-25). The invention also discloses a method of producing material through electrical forming of fibre from a solution which involves deposition of microfibres with diameter 5-10 mcm onto an electrode from a polysulphone-dichloroethane-electrolyte system, and simultaneous deposition onto the electrode of nanofibres with diameter 300-500 nm from a polydiphenylene phthalide-cyclohexanone-dimethylformamide-electrolyte system. ^ EFFECT: invention increases efficiency of cleaning gases at high temperatures. ^ 3 cl, 1 tbl, 1 ex
