The present invention relates to a low friction member having seaweed-type nanotubes, the nanotubes which protrude like seaweed on the surface of a base material being concentrated in the moving direction of a sliding member, thereby improving the fluidity of a liquid lubricant, thus enabling the effective reduction of surface friction.

Such present invention comprises: a base material which has a plurality of dimples formed on the surface thereof so as to reduce friction occurring due to the surface contact of a sliding member; a fixing material which is filled inside the dimples; nanotubes which are buried in the fixing material and protrude to the outside by means of the surface processing of the fixing material; and a liquid lubricant which is coated on the surface of the base material, wherein, as the protruding nanotubes become concentrated in the moving direction of the sliding member, the fluidity of the liquid lubricant is improved, thereby enabling the effective reduction of surface friction.

The present invention relates to a low-friction member imitating shark skin and a manufacturing method therefor, the low-friction member implementing a structure similar to shark skin and having riblets by stacking, in layers, composite particles formed by attaching spherical particles on the surfaces of plate-shaped particles, and thus the low-friction member has excellent low-friction characteristics. The present invention comprises: a base plate; plate-shaped particles stacked in layers on the surface of the base plate in the form of scales; and a plurality of spherical metal lubricating particles having a size smaller than that of the plate-shaped particles, and coated on the surfaces of the plate-shaped particles, wherein the metal lubricating particles are arranged in the form of a bridge connecting the base plate and the plate-shaped particles, and the plate-shaped particles to each other.
