Introduction

Sami Miguel El Awad Azrak is an accomplished inventor based in Midland, MI (US). He has made significant contributions to the field of cellulose nanomaterials, holding two patents that showcase his innovative approaches to processing and applications.

Latest Patents

One of his latest patents is focused on the continuous processing of cellulose nanofibril sheets through conventional extrusion. This novel method allows for the preparation of sheets comprising cellulose nanofibril (CNF) and carboxymethyl cellulose (CMC). The process utilizes single screw extrusion to continuously process mechanically fibrillated cellulose nanofibrils into sheets. The water-retention ability and stability of CNF suspensions containing various processing aids were assessed through centrifugation and zeta potential analysis. Highly loaded pastes containing the best performing processing aids and CNF were prepared using a Brabender with Banbury mixer-head, demonstrating that highly loaded CNF pastes can be processed in under 40 minutes, significantly reducing preparation and drying time.

Another notable patent involves a cellulose nanomaterial (CN) based waterborne polyurethane coating. This invention relates to a novel coating and methods of making and using it, further expanding the applications of cellulose nanomaterials in various industries.
