Abstract
Porous polysiloxane microspheres may be formed using a double emulsion (W/O/W) and double reaction process. The methods generally comprise forming a first emulsion and reacting components of the emulsion phases to form reinforced hydrogen gas pockets. The first emulsion is then combined with a solvent to form a second emulsion comprising a plurality of microspheres making up the dispersed phase. The microspheres comprise the reinforced gas pockets encapsulated by a polysiloxane, which are cured and recovered. The microspheres are particularly useful as fillers for low density composite materials and sensor applications.
