Abstract
Significant research in non-toxic flame retardants (FR) has been performed in recent years since the dangerous consequences of halogenated FR were found. As early as the 1970’s, carcinogenic the side effects of halogenated compounds were being acknowledged. Since the early 2000’s halogenated FRs began being phased out of use due to these negative side effects. Since then, significant research has been exploring alternative effective flame retardants. Ferrocene (Fc) is a promising alternative to halogenated FRs due to its nontoxicity and FR properties. This research will report on the synthesis of 1,1’-di(1-hydoxyethyl) ferrocene (DHEFc) and its incorporation into a polyurethane. A study of the flame retardant properties of DHEFc and/or Halloysite were explored using varying amounts of DHEFc and/or Halloysite that were then combined with BiOH 2100 followed by toluene di-isocyanate. The mixtures were poured onto a glass pane and drawn with a doctor’s blade to form thin films. FT-IR spectra, H-NMR, COSY, thermal stability by TGA, and horizontal flame testing of the films will be reported.
