| Abstract: | The contact of a hydrogel during the rotational shearing on a glass surface in concentrated polymer solution was observed in situ. Dynamic contact patterns that rotate in-phase with the rotational shearing of the gel were observed for the first time. The contact patterns with a periodicity in the circumferential direction appeared and became fine with the shearing time. The patterns appeared more quickly at an elevated sliding velocity, polymer concentration, and normal pressure. Furthermore, the softness of the gel also substantially influenced the characteristics of the patterns. The pattern formation was discussed in terms of the non-linear rheology of the polymer solution at the rotational soft interface. |
