Monodisperse hollow silica nanospheres with an outer diameter of ~300nm were prepared for the comparison of thermal conductivity with similar solid silica nanospheres. It was found that the thermal conductivity of the hollow nanospheres was lower than that of the solid silica nanospheres....
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 ...
