Title: Innovations of Gamini Samaranayake
Introduction
Gamini Samaranayake is a notable inventor based in Blacksburg, Virginia. He has made significant contributions to the field of materials science, particularly in the development of innovative coatings and hydrogels. With a total of three patents to his name, his work showcases a blend of creativity and scientific rigor.
Latest Patents
One of his latest patents involves chitin-based coatings. In this invention, a chitosan starting material is combined with a dilute organic acid to produce a chitosonium ion complex. This complex can be cast, sprayed, extruded, or otherwise processed to create filaments, coatings, fibers, or similar products. Heat is then applied to convert the chitosonium ion complex into a N-(C.sub.1-30)acyl glucose amine polymer. Another significant patent focuses on the chemical modification of pre-shaped hydrogels in a non-aqueous medium. This method allows for the reaction of highly expanded, porous hydrogel particles, such as spherical beads, under pseudo homogeneous reaction conditions without the presence of water. The process involves a three-step procedure that includes solvent exchange into a water-free solvent, reaction under non-aqueous conditions, and final solvent exchange into water. This innovative method has been demonstrated for crosslinking fluorinating beads and esterifying beads in reactions involving multifunctional free carboxylic acids.
