Fabrication of size-controllable hollow nano-spheres based on polyimides composites
In this communication, uniform and size-controllable PI composite hollow spheres were fabricated by means of in situ favorable adsorption within sulfonated polystyrene hollow sphere templates. It was calculated that more than 33 wt.% polyimides existed on the resulting composite hollow spheres, which endued them with excellent high-temperature resistance. The high carbon remaining and favorable shape reservation of the PI-based composite hollow spheres made them promising precursors of carbon hollow spheres. (C) 2009 Elsevier B.V. All rights reserved.
