摘要

The invention relates to a foamed material and to a method for the production of said foamed material. According to the inventive method, foamed material is produced with nanosized foam bubbles Z 1 without the need to surmount the energy barrier which usually occurs during phase transitions and nucleation processes. The aim of the invention is to produce a foamed material in a controlled manner, said material having a foam bubble density of 10¹²-10¹⁸ per cm³ and an average foam bubble diameter of 10 nm-10 mum hat. The inventive method is based on the dispersion of a second fluid K 2 the form of pools Po in a matrix of a first fluid K 1 involving supramolecular interaction of an amphiphile K 3. The first fluid K 1 is provided as a matrix in the reaction chamber RK and the second fluid K 2 is provided in pools. The second fluid K 2 is transformed into a near-critical or overcritical state with a near-liquid density by modifying the pressure and/or temperature. The second fluid K 2 is provided entirely or almost entirely in the form of pools which are evenly distributed in the entire first fluid K 1 . Pressure discharge causes the second fluid to return to a state of gaseous density while the pools are blown to form nanosized foam bubbles Z 1.
