Influence of the coagulation bath on the nanostructure of cellulose films regenerated from an ionic liquid solution

Cellulose membranes were prepared from an EMIMAc ionic liquid solution by nonsolvent-induced phase separation (NIPS) in coagulation baths of water–acetone mixtures, ethanol–water mixtures and water at different temperatures. High water volume fractions in the coagulation bath result in a highly reproducible gel-like structure with...

Different agglomeration properties of PC₆₁BM and PC₇₁BM in photovoltaic inks-a spin-echo SANS study

Fullerene derivatives are used in a wide range of applications including as electron acceptors in solution-processable organic photovoltaics. We report agglomeration of fullerene derivatives in optically opaque solutions of PC₆₁BM and PC₇₁BM, with concentrations ranging from 30 mg mL^-1 up to 90 mg mL<sup>-1<...
