Abstract
Aspects relate to 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 (e.g., an alkylbenzene sulfonic acid) and the second mixture to produce a third mixture, 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, and (optionally) defining or modifying the glass transition temperature of the polymer or polymer-derived particles comprising polyfurfuryl alcohol.
