Synthesis of Hydrophobic and Oleophobic Nylon-Cotton Fabric Through Microwave Catalyzed Silane Attachment (PREPRINT)

Abstract

We report a microwave induced attachment of a perfluoroalkylsilane to produce highly hydrophobic and oleophobic (H -O) nylon -cotton material. A series of experiments explored the parameters of curing intervals, curing time, base catalysis, and concentration of silane. A single microwave interval of five seconds was able to produce H -O fabric when treated with a NH4OH catalyzed solution of 1% perfluorosilane in isopropyl alcohol. Contact angles for samples treated in a multiple dip -cure sequence averaged 148 degrees with water and 135 degrees with n-hexadecane, with no droplet absorption either within 60 hours (n-hexadecane) or until complete evaporation (water).
