摘要:
Chemically modified carbon nanotubes composed of carbon nanotubes (such as multiwall carbon nanotubes) having carboxyl groups on the surface thereof and polymeric aniline (such as 3- to 300-meric aniline) bonding thereto through the amide linkage. The chemically modified carbon nanotubes exhibit good affinity with organic solvents and readily disperse into organic solvents.

A fine carbon fiber having linearity, each fiber filament of the carbon fiber having a bending angle of 30° or less with respect to the longitudinal direction of the fiber filament, and including a hollow space extending along its axis, and having an outer diameter of 1 to 1,000 nm, an aspect ratio of 5 to 1,000, and a BET specific surface area of 2 to 2,000 m2/g, wherein the average interlayer distance (d002) of the carbon fiber at a (002) plane is 0.345 nm or less as measured by means of X-ray diffractometry, and the ratio of the peak height (Id) of the band at 1,341 to 1,349 cm−1 in a Raman scattering spectrum of the carbon fiber to that of the peak height (Ig) of the band at 1,570 to 1,578 cm−1 in the spectrum (Id/Ig) is 0.1 to 2. The fiber exhibits excellent dispersibility in a matrix.

A robot according to this invention includes a driving mechanism, a first arm rotatably connected to the driving mechanism, a second arm rotatably connected to the first arm, and an X-shaped end effector rotatably disposed at the distal end of the second arm. Of the four distal ends of the end effector, two distal ends include holding units which can hold substrates in one direction, and the remaining two distal ends include holding units which can hold substrates in the opposite direction.

The present invention relates to a method for producing a resin composition having a crystallized and orderly arranged structure. The method comprises kneading an amorphous thermoplastic resin with a resin crystallization promoter to form a mixture, wherein the resin crystallization promoter comprises vapor grown carbon fibers, each fiber filament of the carbon fibers having a diameter of 0.001 μm to 5 μm and an aspect ratio of 5 to 15,000, the fibers having undergone a graphitization at 1,500° C. or higher, and subsequently subjecting the mixture to annealing at a temperature of from 55° C. higher than the glass transition point of the resin to a temperature 75° C. higher than the glass transition point of the resin. The crystallization promoter and annealing provide a thermoplastic resin composition, which, when molded, exhibits improved strength and tribological characteristics.
