25 Claims

1. A method of particle fabrication, comprising:

mixing at least one stabilizing compound with an aqueous solution to produce a first mixture;

mixing furfuryl alcohol, a derivative of furfuryl alcohol, or a mixture thereof, into the first mixture to produce a second mixture;

heating the second mixture;

mixing a surfactant comprising an acid moiety and the second mixture to produce a third mixture; and

initiating a polycondensation reaction of the furfuryl alcohol, the derivative of the furfuryl alcohol, or the mixture thereof, in the third mixture to produce polymer or polymer-derived particles comprising polyfurfuryl alcohol.
