Abstract

A method for producing a liquid foam with gas pores, comprises the steps of:a) Providing a suspension at a first pressure, whereby the suspension comprises suspended nanoparticles in a liquid;b) Subjecting the suspension to an underpressure, whereby the underpressure is a pressure lower than the first pressure;c) Foaming the suspension for producing gas bubbles in the suspension while the suspension is kept at the underpressure, such that gas pores comprising a gas volume surrounded by nanoparticles at the gas-liquid interface are produced;d) Releasing the underpressure in order to obtain the liquid foam with suspended gas pores.
