Embodiment 1
[0039] figure 1 The structural representation of the transparent conductive hydrogel with one-sided self-adhesiveness prepared for the present invention, the specific preparation process is as follows:
[0040] 1. Add 5.5g of sodium dodecyl sulfate (SDS) into 40ml of deionized water, and magnetically stir at 800 rpm for 30min at 25°C to obtain a clear solution A;
[0041] 2. Add 1.75ml of lauryl methacrylate (LMA) to solution A, stir magnetically at 500 rpm for 3 hours at 25°C; then add 10g of acrylic acid (AAc), stir at 500 rpm at 25°C Stir magnetically at 500 rpm for 20 min until completely dissolved, then add 80 mg of initiator ammonium persulfate and stir for 30 min, finally add 300 μl butyl acrylate (BA), stir magnetically at 500 rpm for 20 min, and mix well to obtain solution B ;
[0042] 3. Ultrasonically defoam solution B for 5 minutes, then pour it into a glass mold (100mm*100mm*2mm), and react at 60°C for 6 hours to obtain a hydrophobic association hydrogel with on...
