POLYURETHANE SHEET AND ITS PRODUCTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a process for dispersing carbon nanotubes capable of easily dispersing carbon nanotubes and a production process of a carbon nanotube dispersion liquid, and also a polyurethane sheet with dispersed carbon nanotubes in the resin and a production process of the polyurethan sheet. SOLUTION: The production process of the carbon nanotube dispersion liquid is characterized in containing a step of preparation of a carbon nanotube dispersion liquid by the addition of carbon nanotubes in a solution containing a surfactant and an adipic acid ester-based plasticizer, and a step of ultrasonic wave treatment of the resultant carbon nanotube dispersion liquid.
