Thin-film coatings on materials that act as repellents against bacteria are nothing new. Indeed, with the emergence of antibiotic-resistant bacteria, other strategies to mitigate the spread of such pathogens have long been the focus of researchers. Such thin films are usually polyelectrolyte complexes (PECs), which are traditionally deposited onto a desired surface layer-by-layer, allowing for […]
COLLEGE STATION, Texas — A Texas A&M doctor is working to develop new non-toxic protective nanocoatings to the clothes worn by our military servicemen and women while serving around the world. Dr. Jaime Grunlan is applying water-based nanocoatings to military clothing with the hopes of adding protecting properties to military clothes. The nanocoating, which includes […]
Thomas Kolibaba (’20) was awarded the NIST National Research Council Postdoctoral Fellowship, funding his postdoctoral research at NIST in Boulder, Colorado following graduation. Natalie Vest (’24) was awarded the Department of Defense (DoD) Science, Mathematics, and Research for Transformation (SMART) Scholarship, an award that offers full research and education funding, as well as internship opportunities […]

Efforts have been made to introduce environmental friendly flame retardants on commercial products. Examples include nanocoatings for polyurethane foams and for fabrics being researched by Jaime Grunlan, of the Polymer Nanocomposites Lab at Texas A&M University in the US. Grunlan has demonstrated it is possible to protect cotton with alternating nanolayers of chitosan and phytic acid. […]
PNC Lab developed nano coatings consists polyvinylsulfonic acid (PVS) and chitosan can prevent the spread of flames on foams used in home furnishings. Moreover the 30-nm-thick film increases the weight of the foam by just 5.5% and doesn’t alter the foam’s stiffness.
A new fire-retardant coating suppresses flames without the toxic effects of some commercially used flame retardants. Torch a piece of furniture foam that’s been dipped in the coating and the flame smolders and snuffs out, new experiments show.The new coating creates a blanket of heavy gas that starves the fire of oxygen.
New coating could protect furniture without causing health concerns
PNC Lab’s technology involves covering every microscopic fiber in a fabric with a thin composite coating of two polymers that exhibit an intumescent effect, producing a protective carbon foam coating when exposed to high temperatures.
Promising alternative packaging engineered by materials scientists in the Polymer NanoComposites Lab suggests “nano-bricks” offer the solution of longer shelf life and superior food preservation.
Article written by the New York Times about the exciting materials research happening at the PNC Lab, and Dr. Grunlan’s push for the values of academic research and higher education in Texas.
“While his research is making waves among scientists, Professor Grunlan has also made a mark outside of his research laboratory.”
