Abstract

Two-dimensional combinatorial thin film libraries are used to rapidly measure the LCST phase boundary of polystyrene and poly (vinylmethyl ether) blends in compositin-temperature space. The film libraries with continuous gradients in polymer blend composition were prepared by a novel film deposition method and annealed on an orthogonal temperature gradient. The phase boundary was visually apparent to the unaided eye on the surface of the sample library, and agreed with conventional light-scattering cloud points. These validated results illustrate how the combinatorial approach can be applied to facilitate rapid discovery and measurements of polymer blend phase behavior.
