Abstract
In this work, sulfonated poly(ether ether ketone) (SPEEK) nanocomposite membranes were prepared with high loading of phosphotungstic acid (HPW) immobilized by polydopamine coated halloysite nanotubes (DHNTs). XPS and FTIR analysis revealed the formation of acid-base interactions between HPW and DHNTs in the nanocomposite membranes, indicating the successful immobilization of HPW on the surface of high aspect-ratio DHNTs, which helped shorten the...
