Abstract: The present method for evaluating an orientation of silver nanowires is a method for measuring an orientation of silver nanowires included in a polyvinyl alcohol film, the method including measuring, using linearly polarized near-infrared light, a first transmittance T1 for polarized light perpendicular to an orientation direction of silver nanowires and a second transmittance T0 for polarized light parallel to the orientation direction of the silver nanowires in a polyvinyl alcohol film including the silver nanowires, and determining an orientation to be high in a case where a ratio (T1/T0) of the first transmittance T1 to the second transmittance T0 is greater than 1, and determining the orientation to be low in a case where the ratio is close to 1.

Abstract: In a method for producing a high-molecular-weight polymer sheet, when a monomer composition including silver nanowires is polymerized, the monomer composition is allowed to stand in a state in which a thickness direction of the obtained high-molecular-weight polymer sheet before the polymerization is a vertical direction, and the silver nanowires in the monomer composition are oriented in the vertical direction and polymerized.
