Method and apparatus for producing AlN whiskers, AlN whisker bodies, AlN whiskers, resin molded body, and method for producing resin molded body

An AlN whisker comprising

• a fibrous AlN single crystal,
• an oxygen atom-containing layer covering the AlN single crystal, and
• a hydrophobic layer covering the oxygen atom-containing layer, wherein
• the oxygen atom-containing layer is formed through incorporation of at least oxygen atoms into the AlN single crystal, and
• the hydrophobic layer comprises a hydrocarbon group.

A resin molded body comprising an AlN whisker having a first end and a second end, and a resin material covering the AlN whisker;

• wherein
• the resin molded body comprises a first surface and a second surface opposite the first surface;
• the first end of the AlN whisker is exposed at the first surface, and
• the second end of the AlN whisker is exposed at the second surface,
• wherein
• the AlN whisker comprises a fibrous AlN single crystal, an oxygen atom-containing layer covering the AlN single crystal, and a hydrophobic layer covering the oxygen atom-containing layer;
• the oxygen atom-containing layer is formed through incorporation of at least oxygen atoms by the AlN single crystal;
• and
• the hydrophobic layer comprises a hydrocarbon group.

A resin molded body, comprising

• an insulating particle,
• a plurality of AlN whiskers covering the insulating particle, and
• a resin covering the AlN whiskers, wherein
• the AlN whisker comprises a fibrous AlN single crystal, an oxygen atom-containing layer covering the AlN single crystal, and a hydrophobic layer covering the oxygen atom-containing layer;
• the oxygen atom-containing layer is formed through incorporation of at least oxygen atoms into the AlN single crystal;
• and
• the hydrophobic layer comprises a hydrocarbon group.
