Abstract
Long-range attractions in aqueous suspensions were observed between polymeric microspheres and also between microspheres and a gel bead. Attractive displacements were consistently seen even between like-charged entities, and they were observed over spans as large as 2 mm. Such behaviors are unexpected, and may reside in a long-range attraction mechanism.
摘要
在聚合物微球之间以及微球与凝胶珠之间观察到了水悬浮液中的长程吸引力。即使在带相同电荷的实体之间也始终能看到吸引位移，并且在长达2毫米的跨度上都能观察到。这种行为出乎意料，可能存在一种长程吸引机制。
