Summary: A method for rapidly determining the modulus of polymer blends was developed. A polymer blend gradient library of poly( L ‐lactic acid) (PLLA) and poly( D , L ‐lactic acid) (PDLLA) was created in the form of a strip‐shaped film and characterized with FTIR microspectroscopy. Nanoindentation measurements were made along the gradients to obtain modulus data over a wide range of PLLA‐PDLLA blend compositions. This novel, high‐throughput approach to material characterization provides engineers with a technique to accelerate the development of materials.Deposition of the polymer composition gradient.
