Abstract

Summary: An approach for the high‐throughput preparation and characterisation of aqueous pigment dispersions is described and evaluated. The use of ultrasonication as a rapid technique for dispersing pigments using polymeric dispersants was developed. The results are comparable to those obtained using time‐intensive conventional high‐energy ball mill processing. The quality of the pigment dispersion was evaluated in a high‐throughput fashion using digital image analysis and the results correlated with particle sizes, determined by photo‐correlation spectroscopy.

## Abstract **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. Nanoi
