Polyether ether ketone-based membranes and their applications

PEEK materials have emerged as a viable substitute for the fabrication of specific membranes
that are utilized in harsh environments. Over the last few decades there has been a large
research effort directed at both the fabrication of membranes using PEEK materials and the
use of these membranes to filter both organic solvents and mixtures. The primary methods for
PEEK-based membrane fabrication are presented in this chapter. These include phase
separation (both thermal induced and non-solvent induced) and novel chemical-induced
crystallization. Representative applications in membrane contactors with organic solvents,
ultrafiltration, and nanofiltration are also methodically shown. Concurrently, a thorough
analysis of PEEK solubility in solvents (modifications either in membrane fabrication or in
monomers) is done. Additionally, the challenges of the present and the opportunities for the
future are covered. This chapter offers helpful advice for designing PEEK membranes in
challenging environments and their specific applications.
