摘要： The present invention concerns the preparation of a porous or "pseudoporous" anisotropic material. The anisotropic material consists of a conglomerate including, on the one hand, discreet micellar units with a configuration which is at least partly tubular and with a structure of the lyotropic liquid crystal type and/or the impressions thereof, and, on the other hand, a matrix based on ceramic polymer with alkoxide recurrent elements, in which the said units and/or their impressions are included, characterised in that it consists essentially of:
mixing an ionic surfactant, water and at least one alkoxide in proportions chosen so that a lyotropic liquid crystal structure can form and a condensation hydrolysis reaction allowing the polymerisation of the alkoxide recurrent elements can take place and optionally eliminating the micellar units so as to make the material porous. The present material can be used for example as a carrier for active molecules in linear and non-linear optics and in catalysis.
