Abstract: In this paper, researchers synthesized monodispersed polystyrene spheres (PS), of a desired size. Generally, PS have a typical diameter ranging from 180 nm to 900 nm. However, the researchers in this study were able to reduce the sphere size, by increasing the polyvinylpyrolidone/styrene weight ratio. The PS were used as models, in order to fabricate hollow silica nanospheres (HSNSs), for thermal insulation applications. With modifications to this silica coating process, HSNSs experienced different surface roughness, however they all showed a thermal conductivity of about 0.02 W/mK.
