Rigid Polyurethane Foam with Ionic Liquid Modified Multi Walled Carbon Nanotubes Composites

The rigid polyurethane (PU) were produced using ionic liquid (IL) modified multi walled carbon nanotubes (MWCNTs) by reaction of palm oil based polyol (POP) with methylene diphenyl diisocyanate (MDI). The 1-butyl-3-methylimidazolium tetrafluoborate (BMIMBF4) used as IL to disperse MWCNTs in PU foam by grinding in ratio 1:3 by weight of MWCNTs to IL till black paste were obtained. The effects of different percentage of modified MWCNTs (0.0 - 3.0 %) on Polyurethane / Multi Walled Carbon Nanotubes / Ionic Liquid (PMI) foam composites were evaluated in density, morphology and compressive strength. The density were increased higher 0.0538 kg / m3 at 3.0 % PMI. The average cell size value higher without addition modified MWCNTs and scanning electron microscopy (SEM) showed inhomogenously structure with addition of modified MWCNTs. Compressive strength with 0.5 % PMI showed the highest value 1.671 MPa compared to other PMI.
