Use the stirring equipment in the sol tank (rotation speed is set to 50r/min, stirring for 15-25min) to continuously stir the gel. After the gel is fully dissolved and uniform, the temperature of the water bath is lowered to 55°C to obtain a molten gel matrix.

向熔融凝胶基质中加入液态内容物(本实施例中的液态内容物为丙二醇),使得丙二醇占终产物总质量的C0%(C0=10、20、30、40、50),编号S1~S5。继续搅拌10-15min,直至熔融凝胶基质与丙二醇充分混合均匀,获得载液凝胶。Add liquid content (the liquid content in this example is propylene glycol) to the molten gel matrix, so that propylene glycol accounts for C 0 % of the total mass of the final product (C 0 =10, 20, 30, 40, 50), numbered S1 to S5.
