Abstract
The present disclosure belongs to the technical field of lubricating material preparation, and specifically relates to a halloysite nanotube (HNT)-encapsulated ionic liquid (IL) microcapsule, a self-lubricating fiber textile composite, and a preparation method and use thereof. In the present disclosure, the preparation method includes the following steps: dispersing a HNT and an alkali metal salt of a saturated fatty acid in water, dispersing a resulting inner surface-modified HNT and an IL in an organic solvent, injecting the IL into the HNT in the mixed dispersion under vacuumizing to obtain an IL-filled HNT, and encapsulating a resulting IL-filled HNT at a tube end with an encapsulating material to obtain the HNT-encapsulated IL microcapsule.
