Provided herein is a method of forming a three-dimensional object in which the polymerizable liquid includes a mixture of (i) a light polymerizable first component, and (ii) a heat polymerizable second component; the heat polymerizable second component comprising (i) a first blocked reactive constituent that is blocked with a volatile blocking group, and optionally (ii) a curative. Upon heating a formed three-dimensional intermediate sufficiently, the volatile blocking group is cleaved and vaporizes out of the three-dimensional intermediate, to form the three-dimensional object. Also provided is a three-dimensional object produced by the method. Further provided is a polymerizable liquid composition useful for carrying out the method, and prepolymers and monomers useful for the polymerizable liquid composition.

Methods, compounds, and compositions described herein generally relate to hemiaminal organogel networks (HDCNs) and methods of forming HDCNs. In some embodiments, a hemiaminal organogel has a plurality of first polymers, each having a first end and a second end, a plurality of second polymers, each having a first end and a second end, and a plurality of trivalent aminal-hemiaminal linkages. The first end of each polymer of the plurality of first polymers may be covalently bonded to a first trivalent aminal-hemiaminal linkage. The second end of each polymer of the plurality of first polymers may be covalently bonded to a second trivalent aminal-hemiaminal linkage. The first end of each polymer of the plurality of second polymers may be covalently bonded to one of the plurality of trivalent aminal-hemiaminal linkages. The second end of each polymer of the plurality of second polymers may be non-covalently bonded.

A thermo-responsive shear-thinning photo-curable composition comprises water, a linear amphiphilic polyether ABA triblock copolymer comprising at least one pendent ene group (*—CH═CH) capable of undergoing a thiol-ene reaction, a water-soluble crosslinking agent comprising two or more methylenethiol groups (*—CHSH), and a photoinitiator. Under non-shear conditions and a triblock copolymer concentration suitable for direct-write printing, the composition is a viscoelastic solid (hydrogel) at a temperature of about 15 C. to about 45 C., and is a free-flowing liquid (sol) between 0 C. and about 10 C. The hydrogel form can be shear-thinned at about 15 C. to about 45 C. to form a sol suitable for a direct-write printer using an extruding print-head. The compositions covalently crosslink when flood-exposed to ultraviolet radiation. The compositions have utility in forming three-dimensional scaffolds for growing living cells.

Cationic antimicrobial polymers have been synthesized by a bulk addition polymerization of a nucleophilic agent comprising two tertiary amines and an electrophilic agent that comprises two leaving groups and an aromatic ring between the leaving groups. The reaction solvent for the polymerization is chosen to allow precipitation of the cationic polymer at the polymerization temperature, thereby limiting molecular weight. Quaternization and polymerization occur concurrently. The cationic polymers can be highly active against Gram-negative and Gram-positive microbes, and/or fungi. The cationic polymers can also be non-hemolytic and non-cytotoxic at the effective concentration against the microbes.
