TRANSPARENT MICROPERFORATED MATERIAL AND PREPARATION PROCESS CYCLOPORE SA ABSTRACT DESCRIPTION The subject of the present invention is a solid material made of microperforated sheet transparent to a wavelength light in the visible or infrared, characterized in that the average distance between two immediately adjacent perforations is at least 5, preferably 7 µm, on each side of the material. Preferably, the average tilt angle of the perforations in the thickness of the material is less than 10 ° or even 5 °. In a particular embodiment, the material is a membrane made from a flexible polymer film with a thickness between 0.1 and 100 u, more generally between 5 and 50 µ, and the perforation diameters being between 0.01 and 15 µ. The membranes obtained according to the invention are particular-useful as support membranes for reading under a microscope optical or infrared spectroscopy. They can also be used as filtration membranes or as culture medium cellular among others. |
