Abstract

Esitatud leiutis käsitleb meetodit kiulise filtermaterjali valmistamiseks elektriketruse meetodil, kusjuures kiududel on lisaks stabiilsele elektreetlaengule täiendavalt triboelektriline laeng. Esitatud meetodi teostamiseks formeeritakse kiud elektrostaatilises väljas sellisest kahest polümeeride lahusest, kus polümeerid omandavad kontakteerumisel triboelektrilise laengu. Kiudude kooslangemise ajal kogumiselektroodile ja samal ajal toimuva kiudude vastastikuse hõõrdumise tõttu omandavad need kiud tavalise elektriketruse puhul elektreetlaengule lisaks vastasmärkidega laengu, st triboelektrilise laengu, mis vastab laengu märgile, mis saadakse kahe polümeeri, mis asuvad triboelektrilise rea erinevates otstes, segunemisel. Tribolelektrilise laengu omandamise tõttu suureneb elektriväli saadud materjali sees ja seetõttu paranevad materjali filtreerivad omadused
