Title: Johannus Maria Bergmans: Innovator in Polymer-Additive Composite Technology

Introduction

Johannus Maria Bergmans is a notable inventor based in Zevenaar, Netherlands. He has made significant contributions to the field of polymer-additive composites, holding two patents that showcase his innovative approach to material science.

Latest Patents

Bergmans' latest patents focus on the development of particles comprising a composite of para-aramid and additive material. The invention details a method for creating a polymer-additive composite particle from a dope by jet spinning the dope to obtain a pulp, fibril, or fibrid. The solvent used in the dope includes N-methyl-2-pyrrolidone, N,N'-dimethylformamide, N,N'-dimethylacetamide, and tetramethylurea. The composition consists of 2 to 95 wt % of a para-aramid polymer and 5-98 wt % of a solid additive material, totaling 100 wt %. The aramid polymer is dissolved in the solvent, and the dope can be coagulated using a rotor-stator apparatus, where the polymer solution is applied through the stator on the rotor. This process subjects the precipitating polymer-additive composite particle to shear forces while in a plastic deformable stage.
