This invention is a resin composition containing 100 parts by weight of a polyamide resin and 0.01 to 50 parts by weight of boron nitride nanotubes. The invention also includes a formed article from the resin composition and processes for the production of the resin composition and the formed article.
摘要:
Spherical boron nitride nanoparticles having an average particle diameter of less than 50 nm is obtained by a method of synthesizing spherical boron nitride nanoparticles including the following steps; heating a mixture of boric acid ester and nitrogen gas in ammonia gas and argon gas to form reaction product; crystallizing reaction product to form precursor of spherical boron nitride nanoparticles; and, heating the precursor in inert gas.
摘要:
By preliminarily measuring the gallium temperature and the length change of a temperature sensing element comprising a carbon nanotube having a continuous column of gallium contained therein, then heating the temperature sensing element installed in a subject to increase the temperature thereof in air, removing the temperature sensing element subjecting to measure the gallium length, and substituting the measured gallium length in a formula, the temperature is measured accurately over a wide temperature range in a micrometer size or less environment.
摘要:
A new nanothermometer comprises, as a temperature sensitive element, a carbon nanotube in which continuous and columnar indium is included, and comprises a temperature-measuring section for measuring the temperature of an environment by measuring the length in the axial direction of the columnar indium, in the temperature sensitive element, which can be changed with a change in the environment temperature. The nanothermometer can be used to measure temperatures in a wide temperature range in an environment having a size of micrometers or less.
