Claim Text:
1. A preparation method of a ceramic membrane, wherein said preparation method comprises: dispersing halloysite nanotubes in organic solvents, wherein polymers are added therein and stirred until a uniform solution is prepared, whereby a spinning solution used for electrospinning is obtained; wherein a weight ratio of said organic solvent to said polymers is between 4:1-9:1; a weight ratio of the halloysite nanotubes to polymer is equal to or less than 1; wherein an electrospining method is applied to obtain composite fibers by using said spinning solution, whereby a polymer and halloysite nanotubes membrane is prepared; wherein said membrane formed from composite fibers is sintered to remove polymers to obtain the nanoporous ceramic membrane.
