ABSTRACT:
Hollow silica and silica-polymer spheres with diams. 720-1000 nm were fabricated by consecutively assembling silica nanoparticles and polymer onto colloids and subsequently removing the templated colloid either by calcination or decompn. upon exposure to solvents. SEM and TEM images demonstrate that the wall thickness of the hollow spheres can be readily controlled by varying the no. of nanoparticle-polymer deposition cycles, and the size and shape are detd. by the morphol. of the templating colloid. The hollow spheres produced are envisioned to have applications in areas ranging from medicine to pharmaceutics to materials science.
