Title: The Innovative Contributions of Jean-Marie Martinet
Introduction
Jean-Marie Martinet is a notable inventor based in Montelimar, France. He has made significant contributions to the field of materials science, particularly in the development of semipermeable membranes. With a total of 3 patents to his name, Martinet's work has implications for various industrial applications.
Latest Patents
One of Martinet's latest patents is for an organomineral semipermeable membrane and its production process. This invention relates to semipermeable organomineral membranes that are usable in reverse osmosis. The membrane comprises a porous inorganic material support coated with a vinylidene fluoride polymer or copolymer-based organic layer. This layer incorporates functional groups that provide the membrane with permeability to water or other solvents. The porous inorganic material support is preferably made from a macroporous substrate coated with a microporous layer, which can be produced from single or mixed metal oxides or hydroxides.
Another significant patent is for a process for the production of porous, permeable mineral membranes. This process involves forming a thin layer of at least one mineral compound on a porous, permeable substrate. The mineral compound is chosen from simple or mixed metal oxides and hydroxides, excluding aluminum compounds. The process allows for the creation of microporous layers with very small pore radii, enhancing the membrane's functionality.
