Title: Emmanuel Puchois: Innovator in Superabsorbent Technologies

Introduction

Emmanuel Puchois is a notable inventor based in Paris, France. He has made significant contributions to the field of superabsorbent materials, holding three patents that showcase his innovative approach to enhancing absorption capabilities.

Latest Patents

One of his latest patents is focused on superabsorbent powders of high absorption and high capillary suction. This invention describes certain mixtures of two superabsorbent powders with differing capillary suctions, resulting in a mixture that approaches the higher value of capillary suction. The resulting mixtures exhibit both high capillary suction and high intrinsic absorption capacity. Another significant patent involves shell/core particulates of superabsorbent polymers. These particulates are designed to be distortion-resistant, with a gradient of partial crosslinking that makes the shells harder and less flexible than the cores. This design allows them to absorb at least 50 g/g of 0.9% saline water, with a modulus of at least 35,000 Pa. Additionally, a bed of saline water gel made from these particulates has a saline water absorption of at least 20 g/g and a porosity of at least 500 g.

Career Highlights

Emmanuel Puchois is currently associated with Elf Atochem S.A., where he continues to develop innovative solutions in the field of superabsorbent materials. His work has significantly impacted various applications, particularly in industries that require efficient moisture management.
