A Facile Route to Construct Si CO Nanospheres with Tunable Sizes.

We report a facile route to synthesize Si CO nanospheres using Pluronic F127/polyvinylsilazane ( PVSZ) mixed micelles as a template, in which PVSZ selectively swells with the PEO core of the F127 micelles. The thermal degradation of the F127/ PVSZ mixed micelles leads to the formation of Si CO nanospheres. The size of the resultant Si CO nanospheres can be tuned in the range from 25 nm to 75 nm by controlling annealing time at 70°C. [ABSTRACT FROM AUTHOR]
