Embodiment 1
[0022] (1) Dissolve 4.6 g of tetraethyl orthosilicate in 2 ml of ethanol, add dropwise 0.75 ml of 2N hydrochloric acid aqueous solution during stirring, and react for 0.5 hour to obtain a silica sol, which is set aside. Take 0.7g of polyvinylpyrrolidone (molecular weight: 1.3 million) and dissolve it in 20ml of ethanol, add 1ml of the above-mentioned silica sol during the stirring process, perform electrospinning after 4 hours, and place the silica fiber mat obtained by electrospinning in a muffle furnace for 600 ℃ for 4 hours to obtain pure silica fibers, see figure 1 (a).
[0023] (2) Disperse 2 mg of the above-mentioned silica fibers in 2 ml of water, then add 2 ml of an aqueous sodium chloride solution of polyallylamine hydrochloride (PAH) with a concentration of 0.1% by mass, stir at room temperature for 0.5 hour, and then The mixed solution was centrifuged three times (the rotating speed of the centrifuge was 3000r / min), and the upper layer solution was taken out each t...
Embodiment 2
[0028] (1) Dissolve 4.6 g of ethyl orthosilicate in 2 ml of ethanol, add dropwise 0.75 ml of 2N hydrochloric acid solution during stirring, and react for 0.5 hour to obtain a silica sol, which is set aside. Get 0.7g polyvinylpyrrolidone (molecular weight 1.3 million) and dissolve in 20ml ethanol, add above-mentioned silica sol 1ml in stirring process, carry out electrospinning after 4 hours, the silica fiber felt that electrospinning obtains is in the muffle furnace 600 ℃ for 4 hours to obtain pure silica fibers.
[0029] (2) Disperse 2 mg of the above-mentioned silica fiber into 2 ml of water, then add 1 ml of a sodium chloride solution with a mass percent concentration of 0.1% polyallylamine hydrochloride (PAH), stir at room temperature for 0.5 hour, and then mix the solution Centrifuge three times (the rotating speed of preferred centrifuge is 3000r / min), all take out upper layer solution every time, keep the sediment at the bottom, add appropriate amount of double distille...
