Sobre IBD

Opracowano serię barwników monomerycznych poprzez diazotowanie różnych związków 2-aminobenzotiazolu i ich sprzęganie z rezorcyną. Barwniki polimerowe przygotowano w drodze polikondensacji barwników monomerycznych z diizocyjanianem heksametylenu (HMDI) i scharakteryzowano je pod kątem masy cząsteczkowej, za pomocą niewodnego miareczkowania konduktometrycznego, analizy termograwimetrycznej, spektroskopii w podczerwieni (IR) i w zakresie światła widzialnego oraz analizy elementarnej. Barwniki monomeryczne scharakteryzowano również za pomocą analizy elementarnej i widm IR. Czystość wszystkich barwników sprawdzono za pomocą chromatografii cienkowarstwowej. Zsyntetyzowane polimery połączono z dostępną w handlu żywicą epoksydową - eterem diglicydylowym bisfenolu A (DGEBA). Badania utwardzania przygotowanych żywic monitorowano za pomocą DSC. Na podstawie termogramów DSC wykonano laminaty wzmocnione włóknem szklanym i scharakteryzowano ich właściwości chemiczne, mechaniczne oraz elektryczne. Wszystkie badania chemiczne, mechaniczne i elektryczne kompozytów przeprowadzono zgodnie z metodami ASTM.
