A new publication of the National Academy of Inventors (NAI) features the materials research of Dr. Jaime Grunlan, the Gulf Oil/Thomas A. Dietz Career Development Professor at Texas A&M university.

Grunlan and his research team have developed a thin polymer coating for use on fabric and on foam used in furniture to prevent the spread of flames. Furniture cushions are made of flammable polyurethane foam that, when burned, puddles at high temperatures, a quality called the “melt-dripping” effect that further spreads fires. Furniture foam must be treated with flame-retardant chemicals that are known to be harmful to human health and the environment. The U.S. National Fire Protection Association has estimated than upholstery and bedding were the first items ignited in an average of 17,300 fires annually, resulting in 871 civilian deaths and millions of dollars in property loss.

Grunlan said that the coating he and his research team have developed consists of a sulfur-based polymer and chitosan, a carbohydrate polymer found in crustacean shells. This new coating could be an environmentally friendly alternative to the toxic chlorine- and bromine-based flame retardants used today in furniture foam.

Grunlan is an associate professor in the Department of Mechanical Engineering, with joint appointments in the interdisciplinary Department of Materials Science and Engineering and the Artie McFerrin Department of Chemical Engineering. He joined the Texas A&M Engineering faculty in 2004 after receiving a bachelor's degree from North Dakota State University and a Ph.D. from the University of Minnesota. In 2007, he received the prestigious National Science Foundation (NSF) CAREER award for his research into controlling the microstructure of high aspect ratio nanoparticles (e.g., carbon nanotubes) using stimuli-responsive polymers.

In 2012, he received the L.E. Scriven Young Investigator Award from the International Society of Coating Science and Technology "for innovative and high-impact research into coating methods and materials for barrier, flame resistance and electronic applications.” He also received the 2010 Carl Dahlquist Award from the Pressure Sensitive Tape Council.
