Influence of Thermoplastic Polyurethane Characteristics on the Water Vapor Permeability and Mechanical Properties of Coated Fabrics

摘要

Stape memory polyurethane(PU) consisting of hard and soft segments has been of research interest since Mitsubishi discovered it in 1988.Microscopically phase-separated structures consisting of hard domain and soft domain are formed due to thermodynamic immiscibility.
