A nanocomposite is provided to realize excellent mechanical strength by virtue of strong attraction force between sulfonated polysulfone and carbon nanotubes, and to inhibit methanol crossover in a fuel cell, thereby realizing improved efficiency and lifespan of a fuel cell. A nanocomposite comprises: carbon nanotubes; and sulfonated polysulfone represented by the following formula 1. In formula 1, R1s are the same or different, and represent a C1-C10 alkyl, C2-C10 alkenyl, C6-C20 aryl or nitro; p is an integer of 0-4; X is -C(CF3)2-, -C(CH3)2- or -P(=O)Y'-(Y' is H or C6H5); M is Na, K or H; m is 0.1-10; n is 0.1-10; and k is a number of 5-500. |
