Title: Siebe Cornelis De Vos: Innovator in Polylactic Acid Technologies
Introduction
Siebe Cornelis De Vos is a notable inventor based in Arnhem, Netherlands. He has made significant contributions to the field of materials science, particularly in the development of polylactic acid (PLA) technologies. With a total of six patents to his name, De Vos has focused on innovative processes that enhance the utility of PLA in various applications.
Latest Patents
One of his latest patents is titled "Process for manufacturing particles comprising polylactic acid." This patent describes a method for producing particles that include a stereocomplex of poly-D-lactide (PDLA) and poly-L-lactide (PLLA). The process involves extruding a melt containing 30-70 wt. % of PDLA and 70-30 wt. % of PLLA through a specialized formation zone in a twin-screw extruder. The formation zone operates at a temperature above the melting point of both polymers but below 220° C. Following this, a finishing zone is maintained at a lower temperature, allowing for the recovery of solid stereocomplex particles. These particles have various applications, including use in fracking fluids, as fillers, and as nucleating agents in the molding of semi-crystalline PLA.
Another significant patent is "Shaped polylactide article and method of preparation." This patent outlines a method for creating shaped articles from stereocomplex polylactide. The process includes melt mixing and solidifying PLLA and PDLA homopolymers in a specific weight ratio, followed by shaping the resulting solids mixture. This innovation further expands the potential applications of polylactic acid in manufacturing.
