Method for Producing a Nanoporous Layer on a Substrate

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method for creating a nanoporous layer on a substrate by mixing at least two types of nanoparticles (A and B) that have different melting points. By depositing their suspension onto a substrate and precisely heating it so that only the lower-melting-point nanoparticles melt and disappear, well-defined pores are left in the structure formed by the remaining, higher-melting-point nanoparticles. The process allows for controlled pore size and distribution by adjusting nanoparticle properties (material, size, shape, ratio) and does not require complex chemicals or cleanroom technology.
