Abstract: The present disclosure relates to photo-polymerizable resins, methods of photo-polymerizing and foaming resins, and foamed polymeric materials. Some disclosed resins comprise: a first monomer; a second monomer; a photo-activated polymerization catalyst; and a thermally activated foaming agent. Some disclosed methods of preparing photo-polymerized and foamed materials comprise photo-polymerizing a resin with a thermally activated foaming agent to obtain a photo-polymerized polymer material; and heating the photo-polymerized polymer material at a heating temperature to obtain the photo-polymerized and foamed polymer material, wherein the thermally activated foaming agent has a foaming onset temperature, and the heating temperature is greater than or equal to the foaming onset temperature. Also disclosed are photo-polymerized and foamed materials. Further disclosed are polymeric structures having a foam.
