  This guide provides a detailed step-by-step procedure for the dispersion of
(6,5) single-walled carbon nanotubes by shear force mixing with the conjugated
polymer PFO-BPy in organic solvents. All processes presented here were
developed in the Zaumseil group at Heidelberg University since 2015 and
represent best practices to the best of our knowledge. In addition to the
detailed instructions, we discuss potential pitfalls and problems, that we have
encountered over eight years of operation and show how to solve them. This also
includes a detailed description of how to maintain and service a shear force
mixer to ensure long operation lifetime. Finally, we show how to expand our
process to the dispersion other nanotube chiralities in electronic-grade
quality and how to treat dispersions for subsequent processing (e.g., thin film
deposition or functionalization).
