Abstract
  • In part I we adapted the recent analytical mean-field theory of polymer adsorption bySemenov et al. to match the numerical lattice theory of Scheutjens and Fleer (SF). Here we calculateexplicitly the contributions of trains, loops, and tails to the adsorbance and their size distributions. Wechoose conditions in the so-called plateau region, which is most relevant from an experimental point ofview. We thus use the “plateau approximation”, where the two simultaneous equations that determinethe proximal length p and the distal length d can be uncoupled. The variations with bulk concentration,chain length, and surface affinity compare quite nicely with the SF numerics. Both a good solvent (at themean-field level) and ϑ solvent are considered; the agreement is better in the former case.
