Abstract: A composite including a plurality of block copolymer chains dispersed in a base polymer, the block copolymer chains including a polymer block (A) and a polymer block (B) having lower affinity for the base polymer than that of the polymer block (A), wherein each of the block copolymer chains has the polymer block (A) at two or more locations of the block copolymer chain, and in at least some of the block copolymer chains, the polymer blocks (A) are at least partially located in the base polymer and the polymer blocks (B) are at least partially exposed from the base polymer.

Abstract: A material comprising: a support 10; and a brush layer 20 containing a brush-like polymer chain assemblage 21 formed of a plurality of polymer chains and a swelling liquid 22, in which a brush layer 20 is swollen with the swelling liquid 22, the brush layer 20 retaining on the surface a lubricating liquid 30, and the swelling liquid 22 contained in the brush layer 20 and the lubricating liquid 30 being phase-separated to form a liquid-liquid phase separation interface 40 in between and a sliding system using the material.
