[0021] Example 1
[0022] The preparation method of a flexible supercapacitor obtained by using polyaniline as electrode material, organic filter membrane as ion permeable membrane, copper foil as electrical contact, PET as packaging material, and KOH as electrolyte:
[0023] Step 1: Cut the organic filter membrane into a size of 6cm×8cm, and wash the surface with degreaser, deionized water and absolute ethanol in sequence;
[0024] Step 2: In a 500mL beaker, add 340mL deionized water, 8mL concentrated sulfuric acid and 3mL aniline monomer, and stir for 30min to make it uniform;
[0025] Step 3: Put the organic filter membrane cleaned in step 1 into the mixed solution obtained in step 2 above, and stir at a constant speed for 2 hours;
[0026] Step 4: Dissolve 2g of ammonium persulfate in 60mL of deionized water, use a dropping funnel to add the ammonium persulfate solution dropwise to the mixed solution immersed in the organic filter in step 3, and stir at a constant speed for 12 hours...
Example Embodiment
[0032] Example 2
[0033] The preparation method of a flexible supercapacitor obtained by using nickel hydroxide as electrode material, organic filter membrane as ion permeable membrane, copper foil as electrical contact, PET as packaging material, and KOH as electrolyte:
[0034] Step 1: Cut the organic filter membrane into a size of 6cm×8cm, and wash the surface with degreaser, deionized water and absolute ethanol in sequence;
[0035] Step 2: Add 10.5g of nickel sulfate to 40mL of deionized water to obtain a uniform nickel sulfate solution; add 2.03g of potassium persulfate to 30mL of deionized water to obtain a potassium persulfate solution;
[0036] Step 3: Mix the nickel sulfate solution and potassium persulfate solution evenly, add 20 mL of 25% (mass fraction) ammonia water to form a mixed solution, and put the organic filter membrane cleaned in step 1 into the mixed solution and stir at a constant speed for 30 minutes;
[0037] Step 4: After the reaction, take out the organic fi...
