Clarkson Scientist’s Research Into “Smart” Clothing Materials Could Lead To New Synthetics With Biomedical Applications

What makes a nanocomposite material “smart”? Consider clothing that can detect the presence of chemical weapons, automatically seal its own pores, and then clean and decontaminate itself. Today the U.S. Department of Defense is funding research for fabric materials that do all these things and are also stronger, more durable, and lighter than current uniforms.

Minko’s research explores responsive functional material based on self-assembly in polymer and colloidal systems. By studying the behavior of single molecules and the assembly of a few molecules, Minko explained, researchers are learning how nature assembles and reassembles molecules to achieve certain properties. Certain natural materials are capable of smart responses via external stimuli such as temperature or an acidic or base environment.

“Skin is a good example of a material capable of smart responses based on outside stimuli,” he said. “The pores open and close based on temperature and humidity and thus help the body to regulate its internal temperature. Our interests are in understanding how nature has programmed these molecules to react this way and then to recreate the process synthetically.”

At Clarkson, Minko has established the interdisciplinary Nanostructured Materials Group with S.V. Babu, professor of Chemical Engineering, and Igor Sokolov, professor of Physics to explore fabrication and study of synthetic and biomaterials at nanoscale, with a special interest in materials for biomedical application, sensors and molecular electronics.

One of Minko’s current projects involves research in self-cleaning fabrics sponsored by the National Textile Center. Made of any common fabric, these materials will utilize a water-repellant, dirt-repellant, environment-friendly coating made of silver nanoparticles. Their wide applications will include hospital and military garments, as well as sportswear, awnings and convertible tops.

Minko’s research is also supported by Procter & Gamble and Xerox, and organizations such as the National Science Foundation, NATO and New York’s Office of Science, Technology and Academic Research (NYSTAR).
