a method of making products with a functional relief surface with high resolution up to 10 nm , which is copied from a template or carrier of the negative relief of the surface , the so - called master . the template of the relief surface is provided with at least one layer of geopolymer composite , applied in a precursor state , in form of a liquid dispersion or grout in plastic or thixotropic condition , whose thickness is the same or greater than the depth of the template relief , at temperatures in the interval from the temperature corresponding to properties of the precursor to the temperature corresponding to thermal decomposition of the precursor , and after hardening of geopolymer composite the layer or layers is / are separated from the template .
