Une gouttelette structurée multicouche destinée à collecter une poussière fine, selon un mode de réalisation de la présente invention, est une gouttelette structurée multicouche formée d'une couche interne et d'une couche externe, qui englobe la surface circonférentielle externe de la couche interne, la couche interne comprenant un solvant et un tensioactif non ionique, la couche externe comprend un électrolyte polymère de manière à être électriquement chargée, et la gouttelette comprend de 0,1 à 20 % en poids du tensioactif non ionique et de 0,1 à 20 % en poids de l'électrolyte polymère sur la base du poids total de la gouttelette. Comme la poussière fine est électriquement collectée par l'électrolyte polymère, qui est la couche externe d'une gouttelette électriquement chargée, et la couche externe est formée de manière à englober la surface circonférentielle externe de la couche interne de telle sorte que l'évaporation de la couche interne est efficacement empêchée, le temps de flottement de la gouttelette est en outre étendu dans un espace spécifique, et ainsi l'efficacité de collecte de poussière fine peut être efficacement améliorée.
