Abstract

We investigated the strength of capillary adhesion (i.e., adhesion caused by capillary effect of a liquid at an interface) of “mushroom-shaped” polysaccharide gels to clarify detailed mechanism under the enhancement of adhesive strength by the special shape. The used gels are not sticky. They can smoothly slide along the flat substrate, and weakly adheres to it due to the capillary adhesion by the water leached from the inside. However, if molded into the mushroom shape, the adhesive strength was remarkably increased. Experimental results show that there exists an optimal proportion of the mushroom shape to exhibit higher adhesive strength. Mechanical reason for the optimal proportion is discussed.
