| 1. A method of forming a composite of an inorganic-thermoset polymer comprising:
(a) contacting the thermoset polymer with a solution of the precursor of the inorganic particulate phase so as to swell the
thermoset polymer
(b) infusing the precursor into the surface region of the thermoset polymer and
(c) subjecting the infused precursor to conditions sufficient to form an inorganic particulate phase having a particle size
less than 1000 nanometers dispersed in the thermoset polymer phase.
