Title: Walter Fickel: Innovator in Porous Polypropylene Technology
Introduction
Walter Fickel is a notable inventor based in Erlenbach, Germany. He has made significant contributions to the field of materials science, particularly in the development of porous, powdery polypropylene. With a total of 2 patents to his name, Fickel's work has implications in various industries, including environmental and chemical applications.
Latest Patents
Fickel's latest patents focus on the production and utilization of porous, powdery polypropylene. The first patent describes a method for obtaining this material by providing a hot solution of polypropylene in pentaerythritol ester as a solvent. The solution is slowly cooled to room temperature, resulting in a solidified mass that can be extracted with an appropriate extractant. The second patent outlines a similar process, emphasizing the mechanical size reduction of the solidified mass before extraction. The resulting porous polypropylene has an apparent density of 0.1 to 0.3 g/cm³, a particle size of 50-700 µm, and an externally accessible porosity of 70-85%. This innovative material can be used for separating hydrophobic substances from aqueous systems, as an oil adsorbent, and as an additive in protective paints.
