文摘
- •
An original soft templating method to obtain mesoporous SiC is described.
- •
Polycarbosilane SiC precursor is grafted onto SBS block copolymer.
- •
Calcination process destroys the copolymer matrix to release porosity in the final SiC.
- •
Raman spectroscopy, gas adsorption, TGA, SEM and SWAXS provide a deepened characterization of the material.
