Liquid Amphiphilic Polymer for Effective Airborne Dust Suppression.

ABSTRACT: Airborne dust is a byproduct of natural and artificial occurrences, including high winds in arid regions and human activities that affect most of the world's population. Watering is the most general practice for reducing airborne dust by wetting the surface of the dust source to agglomerate dust particles via capillary effect, increasing the aerodynamic diameter of (ultra)fine particles and reducing dust emission. However, the short-term effectiveness due to fast water evaporation, requiring frequent watering, is a major disadvantage. Herein, we utilized biocompatible liquid polymers as additives in water to prolong moist conditions of dust sources due to their liquid state. After the water evaporated, liquid polymers maintained moisture on dust sources, resulting in significantly reduced
