Embodiment 1
[0130] Embodiment 1. Preparation of 1-butyl-3-methylimidazolium chloride (BCl)
[0131] Preparation of 1-butyl-3-methylimidazolium chloride (BCl): 1-butyl-3-methylimidazolium chloride was prepared by the following method: 1-methylimidazole and 1-chloro A mixture of butane (molar ratio 1:1) was heated for 24 h, followed by three washes with ether. The chemical structure of ionic liquids is given by 1 H NMR confirmed and shown in Scheme 1(I). The structure of another ionic liquid, 1-ethyl-3-methylimidazolium acetate, purchased from Aldrich is shown in Scheme 1(II).

[0133] Scheme 1. Chemical structures of 1-butyl-3-methylimidazolium chloride and 1-ethyl-3-methylimidazolium acetate
[0134] 1 H NMR (D 2 O as solvent, d, ppm) spectrum consists of the following peaks: 8.606 (N-CH-N, s, 1H), 7.374 (N-CH-CH, s, 1H), 7,327 (N-CH-CH, s, 1H), 4.095 (N-CH 2 , t, 2H), 3.789 (N-CH 3 , t, 2H), 1.747 (N-CH 2 -CH 2 , m, 2H), 1.229 (N-CH 2 -CH 2 -(CH 2 ) 2 , m, 2H), ...
Embodiment 2
[0135] Embodiment 2. Preparation of cellulose solution
[0136] Cellulose solutions were prepared by adding 0.02 g of different grades of cellulose to 19.98 g of each ionic liquid, then heating the mixture with an oil bath at 90° C. for 1 hour while stirring for 1 hour. After cooling to room temperature, the clear solution at a concentration of 0.1% was used.
Embodiment 3
[0137] Example 3. Preparation of electrospun carriers
[0138] All electrospun supports, including PAN, cross-linked PVA, PA, nylon-6, PES, and PSF, were performed in the laboratory using conditions similar to those described in U.S. Application Serial Nos. 11 / 664650 and 11 / 951248 prepared (except for PA and Nylon-6 vectors, which were obtained from Donaldson and DuPont, respectively), the US application sequence is hereby incorporated by reference in its entirety for all purposes.
[0139] PAN electrospun carrier: the fiber diameter is about 500nm, and the carrier thickness is 40-50μm;
[0140] PVA electrospinning carrier: the fiber diameter is about 230nm, and the carrier thickness is 40-50μm;
[0141] PA electrospun carrier: the fiber diameter is about 200nm, and the carrier thickness is 5-20μm;
[0142] Nylon-6 electrospun carrier: the fiber diameter is 500-1000nm, and the carrier thickness is about 20μm;
[0143] PES electrospun carrier: the fiber diameter is about 500...
