Embodiment 1
[0036] The first step, synthesis of St-g-P (BAS) copolymer: first weigh 5g of starch and add it to a three-necked flask equipped with a condenser tube, then add 100mL of distilled water, place it in a constant temperature magnetic stirrer, pass nitrogen protection, and heat the oil bath to 80°C, stir for 30min until the starch is gelatinized, add 0.2g of initiator ammonium persulfate, and stir for 20min; then add 7.5g of butyl acrylate and 7.5g of styrene monomer, react at 70°C for 4h, and naturally cool to room temperature , precipitated and washed the copolymer with an appropriate amount of absolute ethanol, vacuum-filtered, and vacuum-dried at 60° C. for 24 hours to obtain a St-g-P(BAS) copolymer.
[0037] The second step, preparation of spinning solution: weigh 1g of St-g-P(BAS) copolymer, add it to 8mL of N,N-dimethylacetamide (DMAc), stir and dissolve at room temperature, and let it stand for 24 hours to remove bubble to obtain spinning solution;
