Experimental results of the adsorption of PS-PMMA diblock copolymers onto alumina surfaces from a solvent that is good for PS and a θ–solvent for PMMA. (a) The number of anchoring points (i.e., surface-bound monomers) per PMMA block adsorbed on the cluster surface as a function of the molecular weight of the PMMA block; (b) the number of adsorbed polymer chains per unit area of cluster surface (in units of nm2) as a function of the molecular weight of the PMMA block; (c) the number of anchoring points per unit area of particle surface (in units of nm2) as a function of the molecular weight of the PMMA block; (d) the number of anchoring points per unit area of particle surface (in units of nm2) as a function of the mass fraction of the PMMA block in the polymer; (e) the number of anchoring points per unit area of particle surface (in units of nm2) as a function of the total molecular weight of the polymer; (f) the number of anchoring points per unit area of particle surface (in units of nm2) as a function of the molecular weight of the PS block in the polymer.
