Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] combine figure 1 , a method for preparing a calcium chloride crosslinked sodium alginate electrically driven membrane of the present invention, characterized in comprising the following processes:
[0020] Sodium alginate and calcium chloride are used for cross-linking reaction according to a certain molar ratio, then glycerin is added as a modifier, and the resulting solution is subjected to ultrasonic degassing and vacuum drying to generate calcium chloride cross-linked sodium alginate electric drive film at one time , including three steps of liquid-phase cross-linking reaction, ultrasonic defoaming treatment and high-temperature drying.
[0021] (1) Liquid phase cross-linking reaction: put 1.5g sodium alginate into 50mL distilled water and place it in a water bath to heat, and stir with a magnetic stirrer to fully dissolve...
