General description
Application
- Pickering emulsion polymerization using a silicon dioxide nanoparticle stabilizer to form molecularly imprinted polymers for steroid recognition.
- Mesoporous silica is used as a catalyst support in the preparation of multiwalled carbon nanotubes (MWCNTs).
- It is used as a ring opening of tetrahydrofuran-dimethanol to 1,2,6-hexanetriol.
- It maybe used to prepare silica/brominated poly(phenylene oxide) nanocomposites membranes for CO2 seperations.
- The composite scaffold of chitosan/chondroitin sulfate/nano-SiO2 was fabricated by lyophilization.
- Nanocomposites preparation of silica, single-wall carbon nanotubes, and graphite nanoplatelets in an epoxy matrix have been reported.6
- Dielectric spectroscopy study of the polystyrene/nanosilica model system has been studied.
- PMMA SiO2 nanocomposites were reported to be synthesized.
