Title: Microfluidic Mixer for Polymer Melts

We present a novel microfluidic mixer for high temperature polymer melts based on the platform of the Multi-sample Micro-slit Rheometer (MMR). The device is essentially a static mixer with eight consecutive units of splitting and recombination flow formed by stacking three stainless steel shims (50 μm thickness). The mixing results show both multilayer and domain/matrix morphologies depending on the channel configuration and blend pair. This mixer will be particularly useful not only as a polymer melt mixer but as a multilayer processor when a limited material quantity (typical sample size ≈ 20 µL) is available.
