An end-grafted flexible diblock copolymer exists a critical adsorption point Tc from a desorbed state to an adsorbed state. The finite-size scaling law is adopted to determine Tc and the crossover exponent φ. The non-adsorbed block B weakens the adsorption of the adsorbed block A. Then the effective influence of the B block is reduced with increase in the length of the A block but it is independent of the length at Tc.
