Abstract:
Materials and methods for preparing a payload-containing microcapsule with walls that have hexahydrotriazine (HT) and/or hemiaminal (HA) structures are disclosed. To an HT small molecule or a HA small molecule, or a combination thereof, in a solvent is added a cross-linking agent, NH4Cl, and a copolymer. The solution is acidified, and a payload agent is added. The HT small molecule and HA small molecule may have orthogonal functionality.
