摘要: Wettability and penetration kinetics of liquid into porous material were studied by the capillary rise method. The mass gain penetrating in a tube filled with glass beads was measured vs. time. Two types surfaces: unmodified (smooth), modified (rough), used to investigate influence surface on wettability kinetics. It found that roughness has significant effect but not contact angle. rate liquids rough be over two-fold greater than for materials (smooth) surface. is well known macroscopic angle flat surfaces. Our experiments showed collection particles does depend their roughness. may suggest microscopic
