Abstract Scope |
Crystallization of thin polymer droplets on a substrate is a complicated process often controlled by substrate-polymer interactions and lattice mismatch. In this work, a diffuse-interface approach is employed to study the crystallization kinetics and morphology of thin polymer droplets on substrates under epitaxial conditions. Experimentally observed spherulites and highly anisotropic needle-like lamellar bundles are reproduced in the simulations, and the effects of polymer diffusivity, anisotropy and interfacial energy on growth kinetics and morphology will be discussed. |
