Halloysite, Halloysite and Halloysite!!, page-72

*Sorry to bombard the board with Halloysite articles at once.
However, THIS paper just came out a couple days ago...

The more the market and ADN holders know of the incredible number of uses for Halloysite, the faster they'll wish to be apart of the story.
The truth is...Halloysite to 99% of the market, is just another word.

With the help of density functional theory calculations, a unique MOF-capped nanotube architecture was initially conceived in this study based on the solution-diffusion mechanism. Then, the novel ZIF-8-capped halloysite nanotubes (ZHNTs) were prepared and incorporated in the polydimethylsiloxane (PDMS) bulk to achieve the mixed matrix membranes (MMMs) for n-butanol permselective pervaporation.

The remarkable characteristic of this membrane was that the HNT lumen (∼25 nm) in ZHNTs provided the exquisite diffusion highway for the penetrants that were first selected through the capping ZIF-8 layer.
Simultaneously, the close connection of ZIF-8 layer on external surface of ZHNTs created the relatively continuous pathways for molecular permeation. As expected, the embedding ZHNTs significantly improved the separation performances of the membranes.

Impressively, the as-obtained membrane acquired a high separation factor of 61.3 (58.7% higher than that of PDMS control membrane) with a comparable flux of 683 g m^-2 h^-1 (2.43-fold as much as that of PDMS control membrane) at 40 °C in the separation of 1 wt% n-butanol aqueous solution.
Moreover, the presence of ZHNTs conferred excellent interfacial compatibility, mechanical properties, and good long-term stability on the resultant membranes.
This study may shed light on the rational design of high-performance MMMs for biofuels recovery from fermentation broths.
