Embodiment 1
[0031] A method for preparing an organic-inorganic hybrid film, the specific preparation steps are as follows:
[0032] Step 1: Mix 10mL of 2mg / mL ethanol solution of graphene oxide with 5mL of 30wt.% ethanol solution of ferric 4-ethylbenzenesulfonate with a mass fraction of 30wt.% and ultrasonically mix for 1h, and the dispersion power is 600w to obtain a mixed solution ;
[0033] Step 2: Heat the mixed solution obtained in Step 1 to 80°C in a polytetrafluoroethylene bottle and dry it for 1 hour to form a film;
[0034] Step 3: Place the film obtained in step 2 in pyrrole steam for 30 minutes to polymerize the pyrrole monomer, then wash it twice in ethanol solution and once in dimethyl carbonate solution to obtain an organic film with a thickness of about 10 μm. Sulfonated polypyrrole covalently modified inorganic graphene oxide membrane, that is, organic-inorganic hybrid thin film.
[0035] from figure 1 It can be seen that the synthesized organic-inorganic hybrid film pr...
Embodiment 2
[0039] A method for preparing an organic-inorganic hybrid film, the specific preparation steps are as follows:
[0040]Step 1: 5 mL of 5 mg / mL ethanol solution of graphene oxide and 5 mL of 50% ethanol solution of ferric 4-ethylbenzenesulfonate with a mass fraction of 50% were ultrasonically mixed for 1 hour, and the dispersion power was 600w to obtain a mixed solution;
[0041] Step 2: Using a glass fiber diaphragm as a filter membrane, the mixed solution in step 1 is filtered by a water pump for 10 hours under reduced pressure to form a thin film;
[0042] Step 3: Place the membrane obtained in step 2 in pyrrole steam for 1.5 hours to polymerize the pyrrole monomer, and then wash it in acetonitrile solution for 3 times to obtain inorganic graphite oxide covalently modified with organic sulfonated polypyrrole with a thickness of about 20 μm Alkene films, that is, organic-inorganic hybrid films.
[0043] Such as Figure 4 As shown, the organic-inorganic hybrid film was place...
