Impacts of Polymer Adsorption on Adhesion Strength at Solid Interfaces.

ABSTRACT: Polymer adhesion on solids is governed by chain aggregation at interfaces, yet isolating intrinsic adhesion strength (G₀) from complex failure modes has remained elusive. Here, a surface and interfacial cutting analysis system (SAICAS) was used to quantify G₀ from thickness-dependent measurements. Polystyrene films with varied molecular weights and poly(methyl methacrylate) with different stereoregularities were analyzed as a function of thermal annealing time. G₀ increased with the growth of the adsorbed layer. At extended annealing times, absolute G₀ was dictated not by molecular weight but by segment-substrate interaction energy and chain conformation influenced by stereoregularity. These findings establish that int
