Abstract
Methods and materials for preparing a covalent 3D nano-object are provided. A diamine or triamine monomer and a monoamine terminated precursor may be reacted to form a star polymer material. A cross-linking polymerization process may in a nanogel core with the monoamine terminated precursor covalently linked to the nanogel core. The covalent 3D nano-object may comprise HT, PHT, HA, and/or PHA materials.
Claims19
A method of forming a star polymer material, comprising:
- providing a triamine monomer;
- providing a monoamine terminated precursor;
- exposing the triamine monomer and the monoamine terminated precursor to an aldehyde material;
- and
- forming a star polymer material comprising a polyhemiaminal or polyhexahydrotriazine material, wherein the polyhemiaminal or polyhexahydrotriazine material comprises an aromatic bridging group.
A method of forming a star polymer material, comprising:
- reacting a triamine monomer with a monoamine terminated precursor comprising a polyether amine terminated with a functional group, to form a polyhemiaminal;
- and
- heating the polyhemiaminal to form a star polymer material comprising a hexahydrotriazine material having a plurality of trivalent hexahydrotriazine groups having the structure
- and
- a plurality of bridging groups having the structure
- K′*)y′, wherein y′ is 3, and K′ is a trivalent radical, wherein the trivalent radical comprises at least one 6-carbon aromatic ring.
A method of forming a star polymer material, comprising:
- providing tris(2-aminoethyl) amine;
- providing a monoamine terminated precursor;
- exposing the tris(2-aminoethyl) amine and the monoamine terminated precursor to an aldehyde material to form a mixture;
- heating the mixture;
- and
- forming a star polymer material comprising a polyhemiaminal or polyhexahydrotriazine material, wherein the polyhemiaminal or polyhexahydrotriazine material comprises an aromatic bridging group.
