AN EXACT ENUMERATION STUDY ON ADSORPTION TRANSITION OF A TETHERED CHAIN AT AN ADSORBING SURFACE
of a single chain with length n attached to a flat surface with m monomers contacting the surface is exactly enumerated. A function of c(n
m) about m and n is obtained. From the function
a scaling law for mean energy of chain is derived
and we estimate the critical point εc = 0.276 and the crossover exponent f = 0.5. The free energy difference between tethered chain and free chain in dilute solution is also studied
which shows the critical adsorption point is about 0.272 for infinite long chain with f = 0.5.
