"G3i’s GreenShield™ multifunctional textile finishes, produced according to principles of green nanotechnology, rely on surface functionalization of nanoparticles to deliver performance"
By incorporating amorphous sicilia nanoparticles into textile finishes, Dr. Josephy Bringley, Dr. Tiechen "Alex" Qiao and Dr. Suresh Sunderrajan were able to reduce the fluorochemicals eight-fold and other chemicals up to thee-fold while retaining the ability of the fabric to repel oil and water.
The concept was inspired by structured plant surfaces that repel water and are self-cleaning. According to Bringley, "We have designed the products up front to be as green as possible, using less chemistry and producing less waste - specifically, less harmful waste. We are using a water-based process that produces an essentially 100-percent yield and significantly reduces the use of volatile organic compounds." Energy usage is reduced because the process occurs at room temperature.
