Bubbling up: Dissolution of CO(2) bubbles in a suspension of colloidal particles chemically induces the assembly of particles on the surface of shrunken bubbles, and thus yields rapid continuous formation of a colloidal armor. This approach maintains the high colloidal stability of particles in bulk, has increased productivity, and allows the formation of bubbles with precisely controlled dimensions.
气泡上浮
二氧化碳气泡在胶体颗粒悬浮液中的溶解会化学诱导颗粒在收缩气泡的表面组装，从而快速持续地形成胶体外壳。这种方法保持了颗粒在本体中的高胶体稳定性，提高了生产率，并允许形成尺寸精确可控的气泡。
