Abstract
- We prepared an octa maleimido functionalized POSS, namely octa(maleimido phenyl) silsesquioxane (OMPS)-reinforced polybenzoxazine hybrid nanocomposites, by using four different types of benzoxazines (BZ-Cy-DDM, BZ-Cy-DDE, BZ-Cy-DDS, and BZ-Cy-Ani). They were synthesized from 1,1-bis(3-methyl-4-hydroxyphenyl) cyclohexane, paraformaldehyde, and aromatic amines (4,4′-diaminodiphenylmethane, 4,4′-diaminodiphenylether, 4,4′-diaminodiphenylsulphone, and aniline) by the Mannich reaction. We used 10 wt.% OMPS in all four polybenzoxazine matrices in order to compare the effect of OMPS on various benzoxazines. They were polymerized through thermal ring-opening polymerization at identical conditions. The thermal properties of the resulting OMPS-reinforced polybenzoxazine hybrid nanocomposites were studied using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The dispersion of OMPS in the polybenzoxazine and nanostructure of the composites were confirmed by X-ray diffraction analysis, transmission electron microscopy, and atomic force microscopy.
