Molecular Approach Towards Novel 0D-Nanocarbon-Based Silicon-Containing Ceramic Composites
Herein, novel 0D-nanocarbon-based silicon-containing ceramic composites were prepared by facile sol-gel synthesis method of chemically functionalized nanodiamonds with tetramethylorthosilicate, followed by polymer-to-ceramic transformation.
The high-temperature evolution of nanodiamond/silica (0D-0D) polymer nanocomposites - up to 1700 °C pyrolysis in Argon - was investigated. X-ray diffraction, FTIR and Raman spectroscopy, N2-adsoption and SEM and HREM were performed in order to understand the conversion of nanodiamond to multilayer-fullerene phase within the matrix, as well as the synergetic effect of component phases on the final properties of the composites.
The results achieved within the present study may allow for designing advanced and highly-defined mesoporous 0D-0D nanocarbon-containing composites with tailored structural features and multifunctional property profiles.
