Abstract
The invention relates to a process for generating a porous material having homogeneous, gas-containing inclusions in the micrometer and sub-micrometer range, and also to the material produced by such process.
Claims12
A process for producing a porous material containing homogeneous gas-containing inclusions in the micrometer and submicrometer range, comprising:
- (a) providing a compact packing of the starting material corresponding to the porous material, in which the individual particles contact one another;
- (b) adding a supercritical gas or supercritical mixture of gases;
- (c) surpassing the glass transition temperature (Tg) of the (starting) material with continuity inversion;
- and
- (d) releasing to atmospheric pressure and solidifying by falling below the Tg of the (starting) material.
