摘要
High-performance superamphiphobic fabrics are very useful in special fields,such as firefighting,rescue,and polar sports.The complicated preparation process,easily damaged surface structure,and high cost drastically limit their commercial application.In this work,we utilized a simple,low-cost superamphiphobic coating to prepare a superamphiphobic aramid fabric(SAF).The excellent repellency to acid/alkali solutions and low boiling point organic solvents has been demonstrated with the contact angle of>150°and>130°,respectively.Additionally,the original color of the fabric can also be maintained,accompanied by superior flame retardancy,strength and comfort with thermal degradation of 361℃.More importantly,SAF displayed excellent durability via 50 standard machine washes,100-min of ultrasonic washing,10-min of UV irradiation,120-min of high-temperature heating,5000 cycles of abrasion,and destructive abrasion by sharp metal.All the results showed the superior performance of our SAF in protective fabrics under extreme environmental conditions.
