Summary:

An omniphobic coating that employs a dual hierarchical micro and nano surface structure was developed. This dual-size structured omniphobic coating was proven to be more durable than the commercial durable water repellant coating such as Quarpel durable water repellent (DWR) coating for at least 20 washes to water, oils, and organic solvents. When this omniphobic coating is applied to textile surfaces, the resulting fabrics have very low interfacial energy, which minimizes surface wetting by water, liquid chemicals, and attraction to dirt. This special dual hierarchical micro and nano coating will be introduced as the preventive technological solution for self cleaning clothing to minimize/reduce soldiers’ logistic burden of field laundering, and also as an effective means to providing enhanced chemical/biological warfare agent protective clothing through minimizing a textile’s attraction to solid and liquid contaminants.
