Abstract

Kinetics of phase separation at air/polymer interface in a binary polymer mixture on evaporation of common solvent is studied. The lateral dimension of the highly anisotropie, pancake-like, minority phase increases with a growth exponent of 2/3 identical to ‘late-stage’ growth under (classical) thermal-quench at interface. In contrast to the thermal-quench, during drying the kinetics depends on the initial condition (i.e., initial concentration, Co) that is rescaled to obtain a master-curve.

Since size of NMP molecule is larger than water, D > 10−9 cm2/sec. However, the films in these studies are not cured to rigid polyimide structure. Thus, conservatively, at 70 °C, we assume D ∼ 10'−9 cm2/sec.
