Abstract: This research studied the effect of the addition of vinyl-modified silica and raw silica additions to polymer-silica nanocomposite foams. Extensive physical property characterization was undertaken after their addition to quantify their influence. TEM found that silica particles added through the vinyl-modified silica dispersed better than the raw silica. This created foams with a higher density and smaller cell size. A slight reduction in the thermal conductivity after the additions was observed. The mechanical strength and thermal stability was much better in foams that had vinyl-modified silica added as opposed to raw silica.
