COMPOSITE STRUCTURES WITH GOOD CHEMICAL RESISTANCE AND HIGH PERMEABILITY TO MOISTURE VAPOR

摘要

Composite structures combining fabric and film are used in applications where barrier protection and moisture permeability are important. For example, protective garments require moisture permeability for the wearer's comfort, and moisture permeable protective covers for equipment to avoid condensed moisture induced corrosion or mold growth. Recently, new ionomers having novel performance (increased selective gas transmission while maintaining mechanical properties) have been developed. In this paper, we discuss their use in film structures which have both good barrier protection,, mechanical properties and appropriate moisture transmission properties.
