Provided is a carbon nanotube (CNT) network which can improve an electrical joint so that a sufficient amount of current flows into a thin film and the amount of current is controlled. A network of CNT or a CNT hybrid material is constructed by distributing, as a node between CNT and CNT in a CNT thin film, a fine particle of an inorganic semiconductor and preferably fine particles of a metal halide, a metal oxide, or a metal sulfide.

The present invention discloses a hybrid (mixed) formulation composition for 3D additive manufacturing and a manufacturing process. The hybrid formulation composition possesses capability of UV radiation curing and thermal curing. The hybrid formulation composition is designed to be cured by UV radiation in the 3D printing/additive manufacturing process and then post cure by heat to get its final properties. The hybrid formulation composition consists of acrylates (oligomer, monomer, and diluent), photoinitiators, and isocyanate-containing prepolymers which comprises polyols (di-ol, tri-ol) and isocyanates. The hybrid formulation composition may also include reaction accelerator, dye, pigment, and fillers. The finished products of the hybrid formulation composition possess rubber-like properties and can be used in the applications such as shoe sole, toys, medical, and wearables goods . . . etc.

Eye enhancement contact lenses are disclosed having patterns configured to change the cosmetic appearance of the wearer's iris and limbus, made using inks containing special effect pigments in sufficient amounts to render the patterns less visible when positioned over the sclera, because of placement or normal lens movement on eye, than the same pattern free of interference pigments, thereby providing a more natural appearance. The special effect pigments comprise muscovite mica, synthetic fluorphlogopite, synthetic aluminum oxides, borosilicates, calcium aluminum borosilicates, silicon dioxide platelets, metal oxide coated muscovite mica, metal oxide coated synthetic fluorphologopite, metal oxide coated synthetic aluminum oxides, metal oxide coated borosilicates, metal coated calcium aluminum borosilicates, metal oxide coated silicon dioxide platelets and combinations thereof. In some patterns, the special effect pigments are more concentrated in the periphery which is most likely portion of the pattern move over the sclera during wear.

Self-sintering conductive inks can be printed and self-sintered with a simple and low-cost process mechanized by exothermic alkali metal and water reaction, with enhanced electrical and thermal performance by liquid metal fusion. Such self-sintering conductive inks may include a gallium-alkali metal component and a water absorbing gel component. After patterning, the self-sintering inks, on reaching a designed trigger temperature (including room temperature), may metallize through a two-step process. Initially the gallium-alkali metal component activates and reacts with water released from the water absorbing gel component. Then the exothermic reaction between the water and the alkali element creates an intense and highly localized heating effect, which liquefies all metallic components in the ink and, on cooling, creates a solid metal trace or interconnect. Post cooling, the metal trace or interconnect cannot be reflowed without a significant temperature increase or other energetic input.
