Patent ID: 10119203

Abstract:
Provided is a glossy member, including: a polymer substrate; and a polymer fiber assembly disposed on the polymer substrate, in which: the polymer fiber assembly has polymer fibers oriented in a given direction; an absolute value of a difference between an average solubility parameter of a constituent material for the polymer substrate and an average solubility parameter of a polymer material of the polymer fibers is less than 5 (J/cm3)1/2; the polymer fibers have an orientation degree of 90% or more; the polymer fibers have fiber diameters of 0.05 μm or more and 5 μm or less; and in at least part of a repeating unit structure in the polymer material, a dipole moment is 0 D or more and 3.50 D or less, and an absolute value of a SOMO is 9 eV or more and 12 eV or less.
