“…R-Gel was first prepared according to the previous preparation method. 33 The detailed procedure was as follows. DA•HCl (5 g), 4 mL of C 6 H 15 N, and 50 mL of CH 3 OH were mixed into a 150 mL single-necked round-bottom flask and left to stand in an ice bath at 0 °C for 30 min to obtain solution A; 2.5 mL of tetrahydrofuran and acryloyl chloride was mixed and sonicated at 0 °C for 30 min to obtain solution B; 5 mL of CH 3 OH and C 6 H 15 N was mixed and sonicated at 0 °C for 30 min to obtain solution C. Solutions B and C were alternately added dropwise to solution A, and stirring was continued in an ice bath for 4 h. Then, the white solid product (DAm, 0.2 g) was obtained by distillation under reduced pressure, extraction (ethyl acetate and 1 mol L −1 hydrochloric acid), and vacuum drying and dispersed into 50 mL of DI water to obtain solution D. Finally, 0.9 g of NIPAM and 150 mL of DI water were mixed into a 500 mL single-necked roundbottom flask and placed in a nitrogen atmosphere for 30 min of bubbling and then warmed up to 70 °C.…”
