Title: THREE-DIMENSIONAL PRINTING WITH SUPRAMOLECULAR TEMPLATED HYDROGELS
Abstract:
The invention provides a supramolecular polymer composition capable of co-assembly to maintain a three dimensional (3-D) macrostructural form after 3-D printing, made of a solvent, a template molecule; and a reactive component. The reactive component can be at least one monomer that is capable of hydrogen bonding with the template molecule to form a 1D supramolecular structure. The template may be an amphiphilic polymer. The monomer has at least two pendant groups capable of covalent crosslinking. The invention also includes a 3-D structure formed by crosslinking a 3-D printed supramolecular polymer composition, which optionally has a mesoporous structure. Also included is a method of manufacturing a 3-D structure by delivering a supramolecular polymer composition onto a surface of a substrate to form the 3-D structure.
