Abstract

In this study, a low viscosity, high performance cyanate ester (CE) resin system was used with non-functionalized and functionalized multiwall carbon nanotubes (MWNTs) to create cyanate ester-MWNT nanocomposites. Effects of three different standard functionalizations (i.e. -OH, -COOH, and -NH2) of MWNTs on their dispersion into the CE resin will be studied. Different mixing instruments, such as a high shear mixer, ultrasonicater, planetary mixer, etc. were used to disperse the nanotubes in the cyanate ester resin matrix. Several processing parameters were examined to produce optimal uniform dispersions of nanoparticles into the resin matrix. The parameters studied were mixing speed and duration, and the combination of different mixing techniques. Polymer nanocomposites (PNCs) morphological microstructures were characterized by transmission electron microscopy (TEM) and high resolution scanning electron microscopy (HR-SEM) to determine whether nanotubes are distributed uniformly within the polymer matrix. Thermogravimetric analysis (TGA) and microscale combustion calorimetry (MCC) were used to study the thermal stability and combustion characteristics of these nanocomposites. Dynamic mechanical thermal analysis (DMTA) was used to determine the glass transition temperature (T g) of the PNCs.
