Abstract:
The invention relates to a method for the retroactive surface modification of fine-textured structures consisting of hard, inorganic materials and to the structures that can be obtained by said method.
Abstract:
The present invention is directed to a process for preparing a foam (FA) with a Poisson's ratio in the range of from -0.5 to 0.3 comprising the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming comprising triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). The present invention also relates to the foam obtained or obtainable according to said process and the use of said foam as for example energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.
Abstract:
The present invention relates to a method for producing porous or fine-particle solid inorganic materials, the surface of which is modified with at least one organic substance, which comprises at least one reactive functional group selected from among hydroxyl groups, carboxyl groups, carbonate groups and oxygen atoms bonded to P atoms, under supercritical conditions, the supercritical conditions being reduced by the addition of an inert organic substance.
Abstract:
The present invention relates to a method for producing a porous, solid oxidic material from a hydrogel of the oxidic material, and the porous, solid oxidic material as such.
