  • METHOD OF SPONTANEOUSLY PATTERNING A POLYMER DURING FRONTAL POLYMERIZATION
    Publication number: 20240026068
    Abstract: A method of spontaneously patterning a polymer during frontal polymerization includes activating an initiation region of a monomer solution to reaction to initiate a polymerization reaction. A polymerization front is generated and propagates through the monomer solution in a radial or longitudinal direction away from the initiation region. The monomer solution is spontaneously heated downstream of the polymerization front by thermal transport away from the polymerization reaction. Once a localized region of the monomer solution reaches a temperature sufficient for spontaneous initiation of another polymerization reaction, a new polymerization front is generated and propagates through the monomer solution in a circumferential or transverse direction.
