Nanoparticles are currently in use across a vast array of consumer products. They find application in scratch resistant coatings, active ingredients in sunscreens, stain repellant fabrics, nanoparticle-strengthened steels, and also broadly to the production, processing, safety and packaging of food. Nanotechnology is conducted at the nanoscale, which is between 1 to 100 nanometers (nm). As comparison, a human hair is about 75,000 nanometers in diameter. For application to polymer composites in particular, nanoparticles having a rod like or whisker shape on the nanoscale are desirable.
Researchers at Arizona State University have invented a cost effective, scalable method to make Aluminosilicate nanorod particles with a controllable shape, having specific nanorod dimensions and high aspect ratio (a length of the nanorod divided by a width of the nanorod). These dimensions may be controlled through synthesis conditions such as water content, pH, reaction time, temperature and materials selection to achieve application-specific diameters of 30–50 nm, and lengths of 200–800 nm.
