Abstract
Combinatorial methods are utilized to study the influence of film thickness, h, and crystallization temperature, T, on the crystallization of isotactic polystyrene. Films with continuous gradients in film thickness were prepared by flow coating and crystallized on an orthogonal gradient temperature stage under an optical microscope. Growth rates, G, were measured as a function of h and T from an optical micrograph library of numerous subregions within the gradient films. We observed that G had a maximum near 180 C and varied inversely to h. A transition from hexagonal plate to spherulitic growth was observed with increasing under-cooling in the thickness range 23 nmCitation
