Abstract
The polyamino acids, polyaspartate and its derivatives, are very effective inhibitors of crystallization. They also have utility as corrosion inhibitors. Particularly when they contain both polyanionic and hydrophobic domains, polyamino acids performed better in bench tests than polyacrylate-based materials as dispersants of mineral particles such as calcium carbonate, hydroxyapatite, kaolin, and iron oxide. The interactions of polyamino acids and crystal surfaces have been visualized at the atomic level by atomic force microscopy, lending insights into some mechanisms of action. Biodegradable and non-toxic polyamino acids can be produced in large quantity at low cost and may become useful in a variety of polymer technologies.
