POLYMER NANOFIBER SHEET AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymer nanofiber sheet high in peeling resistance and mechanical strength, and high in specific surface area.SOLUTION: A polymer nanofiber sheet 1 is formed by accumulating and three-dimensionally entangling polymer nanofibers 2 including a polymer. The polymer nanofiber sheet 1 comprises a low-molecular organic compound including at least one 4-membered or more cyclic structure having an ether bond. A difference between an average solubility parameter of the polymer and an average solubility parameter of the low-molecular organic compound is less than 8 (J/cm).SELECTED DRAWING: Figure 1
