    Abstract: The invention provides a method of preparing hydrophobic silica particles comprising (a) providing an aqueous colloidal silica dispersion comprising about 5-70 wt.% of silica particles having an average overall particle size of about 10-1000 nm, wherein the silica particles comprise surface silanol groups, (b) combining the silica dispersion with about 3-75 µmole/m2 (based on the BET surface area of the silica) of a silyl amine treating agent and optionally with other ingredients to provide a reaction mixture, wherein the reaction mixture has a pH of about 7 or more, and comprises no more than about 50 wt.% of an organic solvent, and (c) drying the dispersion to provide hydrophobic silica particles. The invention further provides a method of preparing a toner composition comprising combining the hydrophobic silica particles as recited above with toner particles to provide a toner composition.

    Abstract: Capacitors, including supercapacitors, are described wherein the electrode contains at least one modified carbon product, wherein the modified carbon product is at least one carbon product having attached at least one organic group. The use of the modified carbon product in the electrodes for capacitors preferably leads to improved capacitance and/or lower internal resistance of the capacitor. Further, the use of modified carbon products in the electrodes for capacitors permits easier manufacturing steps for the production of capacitors.
