In the technical field of reconnaissance, target location, target tracking and arms technology, IR sensors are increasingly used for making the entire battlefield transparent up to far into the opponents′ area. An effective method of neutralizing or obstructing the effect of the IR sensors consists in cutting off the line of sight by smoke systems. The liquid smoke compositions are interested for their low cost, high yield speed and high yield efficiency. However, earlier liquid smoke compositions can absorb or scatter electromagnetic radiation only in the visible range, but not in the IR range. Therefore, the study on anti-infrared liquid smoke composition has important military significance.
