An object of the present invention is to provide a method for manufacturing a microscopic bolometer film and a bolometer using the same via a simple method.

The present invention relates to a bolometer manufacturing method including: forming an interlayer having a function that enhances binding between a substrate and a semiconducting carbon nanotube, in a predetermined pattern shape on the substrate; and providing a droplet of a semiconducting carbon nanotube dispersion liquid on the formed interlayer.

An object of the present invention is to provide a bolometer having a high TCR value and a low resistance, and a method for manufacturing the same.

The present invention relates to a bolometer manufacturing method including: fabricating a set of two carbon nanotube wires that are approximately parallel to each other at edges of a line shape, or fabricating a circular shape carbon nanotube wire at a circular circumference of a circular shape, by applying a semiconducting carbon nanotube dispersion liquid in the line shape or the circular shape on a substrate, and drying the dispersion liquid, a width of each wire being 5 μm or more; and connecting a part of each wire to a first electrode and a second electrode.

A method for making a carbon nanotube composite catalytic film includes providing a carbon nanotube film and providing a precursor solution including iron nitrate, nickel chloride, and molybdenum pentachloride. The precursor solution is placed on the carbon nanotube film, to obtain a precursor film. The precursor film defines multiple through holes spaced apart from each other. The precursor film with the multiple through holes is annealed and a sulfur power is applied during annealing the precursor film with the multiple through holes.

Fabrics that have unique mechanical properties are comprised of fibers that have been reacted to provide carbon nanostructures covalently grafted to these fibers so that the entanglement and/or the reactive bonding between adjacent fibers creates a hierarchal structure reinforcement of the fabric. This entanglement and/or reactivity is also effective for developing reinforcement between plies of structural fabric composites in order to enhance inter-laminar shear strength and mechanical properties.

The present invention relates to using modified cellulose (e.g., nitrated cellulose) for separating carbon nanotubes (CNTs). A raw mixture of CNTs of different structures or chiral angles (chiralities), can be separated into fractions, based on their selective permeation through a separation column filled with nitrated cellulose. The present invention is particularly useful in separating semiconducting CNTs and metallic CNTs.

A method of preparing a carbon nanotube monolayer film includes applying a bifunctional hydrogen-bond linker onto a substrate to prepare a surface-treated substrate, mixing carbon nanotubes having a heteroatom-containing aromatic polymer coating film with a hydrophobic solvent to obtain a composition and contacting the surface-treated substrate with the composition, and heat-treating the surface-treated substrate contacting the composition.

A light absorber preform solution includes a solvent, a plurality of carbon nanotubes entangled with each other to form a network structure, and a plurality of carbon particles in the network structure. The plurality of carbon nanotubes and the plurality of carbon particles are in the solvent.
