Abstract

The frictional behavior of the two kinds of high-strength gels, which were double network (DN) gels and shape memory gels (SMG), was studied. By using a commercial measuring instrument with an empirical fitting function, the coefficient of dynamical friction for the DN gels and the SMG was determined. The velocity dependence of the coefficient looked roughly similar for both the DN gels and the SMG, however the details of the dependence were different. The coefficient of the DN gels was smaller than that of the SMGs. The coefficient decreased as the normal force increased. This normal force dependence was observed for the DN gels previously, however for the first time for the SMGs. The differences of both the velocity and normal-force dependences between the DN gels and SMG were discussed in relation to their mechanical properties determined in the previous studies. It implied that the difference of the dependences was possibly related to the different softness of the gels.
