1. A coated heat exchanger structure which is produced according to a method whereina) a dispersion is formed on a substrate or is applied on a substrate after production, and
b) film formation and/or crosslinking with formation of a film layer is or are effected on the dispersion at temperatures of 0° C. to 300° C.,wherein the dispersion comprises:(i) at least one porous sorbent selected from the group consisting of mesoporous alumino- and silicon compounds, metal-organic frameworks (MOFs), porous coordination polymers (PCPs), zeolite-imidazolate networks (ZiFs), mesoporous molecular sieves (MCMs), activated carbons, carbon molecular sieves, hexacyanometallates and mixtures thereof,
(ii) at least one binder, wherein the at least one binder consists of a monomer or monomers, which is or are crosslinked via a crosslinker, wherein the monomer or monomers are selected from the group consisting of aliphatic monoorganosiloxanes, olefinic monoorganosiloxanes, aromatic monoorganosiloxanes, aliphatic diorganosiloxanes, olefinic diorganosiloxanes, aromatic diorganosiloxanes, aliphatic triorganosiloxanes, olefinic triorganosiloxanes, aromatic triorganosiloxanes, and mixtures thereof,
(iii) at least one organic solvent;
wherein the mesoporous alumino- and silicon compounds are selected from the group consisting of zeolites, aluminophosphates, silica aluminophosphates, and metal aluminium phosphates, and wherein the coated heat exchanger structure comprises a film layer containing at least one porous sorbent dispersed within the at least one binder.
