In order to clarify friction characteristics by a combination of periodic surface patterns, friction tests were carried out using micro/nano groove patterns prepared on cylindrical surfaces. For the combinations between microgroove surfaces, the friction coefficients were affected by not only the groove geometry but direction of sliding. For the combinations between two nanostripe surfaces, the maximum friction coefficients were measured for the configuration that the grooves of the nanostripe on both surfaces are perpendicular to the sliding direction, and for the configuration that the grooves of the nanostripe on both surfaces are orthogonal to each other. For the former configuration, the sticking force generated by the slope of the microgroove was dominant in the measured friction force.
