Super-elastic flexible three-dimensional composite ceramic nanofiber block as well as preparation method and application thereof
The invention discloses a super-elastic flexible three-dimensional composite ceramic nanofiber block as well as a preparation method and application thereof. The preparation method comprises the following steps that: polyvinylpyrrolidone is dissolved in ethanol to obtain a solution serving a spinning precursor solution; a substance source of a ceramic material and a corresponding solvent and auxiliary are added into the precursor solution to form a uniform electrospinning solution, fiber membranes obtained through electrospinning are collected, and the membrane thickness is 10-30 microns; and meanwhile, under the condition that the humidity is 40-60 wt.%, the electrospun fiber membranes are simply overlapped in modes of folding, cutting or the like, adhesion is carried out by utilizing the volatility of solvents of the fiber membranes, and then calcination is carried out in air or other atmospheres to obtain a three-dimensional ceramic fiber block. The obtained three-dimensional ceramic fiber block has rich pore structures, and can be applied to the fields of air purification, especially high-temperature waste gas treatment and the like because of the excellent thermal stability and chemical stability of the ceramic fibers.
