POLYPROPYLENE CARBONATE CONTAINING SOLUTION, POLYPROPYLENE CARBONATE CONTAINING LAYER AND MANUFACTURING METHOD OF COMPOSITE MEMBER
Document Type and Number:
Japanese Patent JP2019167520
Kind Code:
A
Abstract:
To provide a polypropylene carbonate containing layer capable of maintaining high liquid repellency even when irradiated with ultraviolet light.SOLUTION: A polypropylene carbonate containing layer of the present invention contains a polypropylene carbonate having an acyl group at a terminal group of a molecular chain. In the polypropylene carbonate containing layer, after at least a surface of the layer is irradiated with ultraviolet light continuously for 15 minutes, a contact angle of the surface is 0.9 or more, when a contact angle of the surface before the irradiation of the ultraviolet light is 1.SELECTED DRAWING: Figure 3
