An aqueous ink composition for inkjet printing on non-porous substrates and a method for forming the same are disclosed. For example, the method includes preparing a primary polymer latex with an aromatic functional group, a hydrogen-bonding group, a flexible side-chain, and an ionic functional group and mixing the primary polymer latex with a secondary latex binder and one or more co-solvents.

The present disclosure provides advantageous sheet stabilized emulsion based inks, and improved methods for fabricating and using such inks. More particularly, the present disclosure provides improved methods for fabricating conductive inks derived from water-in-oil emulsions stabilized by sheets exfoliated from layered materials (e.g., substantially pristine and non-oxidized graphite or hexagonal boron nitride), and related methods of use. A layered material (e.g., substantially pristine and non-oxidized graphite or hexagonal boron nitride) can be exfoliated into individual sheets, and these sheets can be utilized to stabilize water-in-oil emulsions. In certain embodiments, by utilizing long chain alkanes (e.g., hexadecane), one can advantageously fabricate emulsions with high viscosity and stability. In this form, the emulsions can be used as inks, thereby advantageously providing an inexpensive route to printing electrically conducting and/or insulating lines and shapes.

Various embodiments relate to a liquid metal particle-assembled network synthesized in various polymers and a method of manufacturing the same. The liquid metal particle- assembled network is configured to include a polymer matrix, first liquid metal particles spaced apart from each other and disposed within the polymer matrix, and second liquid metal particles that connect the first liquid metal particles between the first liquid metal particles within the polymer matrix. In this case, the size of each of the second liquid metal particles may be smaller than the size of each of the first liquid metal particles.

Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.
