文摘
We present microscopy investigations on the morphology of crystals of poly-2-vinylpyridine-polyethyleneoxid diblock copolymers (P 2 V P - PEO) in thin films with thicknesses below and above the thickness of a single lamella. For crystallisation temperatures above 45°C, nucleation is highly unlikely. Thus, the resulting morphologies represent essentially single crystals, allowing us to relate morphology to the kinetics of crystal growth. In several examples we demonstrate the influence of thermal history and film thickness on molecular orientation and pattern formation during crystal growth. We discuss the analogies and differences between crystallisation of small molecules and polymers.
