Embodiment 1
[0070] The specific steps of the preparation method of the triboelectric nanogenerator based on the fish gelatin film are as follows:
[0071] (1) Dry the discarded fish scales in the sun and wash them with tap water to remove any visible dirt;
[0072] (2) Treat the dried fish scales with 0.1M sodium hydroxide (pH=12) for 1 h. The treated fish scales were washed with tap water until the pH value dropped to about 7.5; then treated with 10% hydrochloric acid for 1 hour to remove minerals. Simultaneously rinse with tap water until the pH drops to around 7.5 again;
[0073] (3) Put 500 mL of water and the treated fish scale into a stainless steel airtight container for hydrolysis, the hydrolysis temperature is 80° C., and the hydrolysis time is 8 hours.
[0074] (4) Use a sieve to separate the solid from the liquid. The liquid filtrate was centrifuged at 2500rpm for 15 minutes to remove any solid residues that may exist in the liquid;
[0075] (5) Transfer 30 mL of the above ...
Embodiment 2
[0086] Use printing paper, PI film, aluminum foil, PET film to replace the fish gelatin film in the present invention respectively, and PDMS film is assembled into triboelectric nanogenerator, specifically comprises the following steps:
[0087] (1) Cut the printing paper, PI film, aluminum foil, and PET film materials into squares with a size of 5cm×5cm;
[0088] (2) Use 400-mesh sandpaper to polish printing paper, PI film, aluminum foil, and PET film to increase surface roughness;
[0089] (3) Configure the PDMS solution, and mix the PDMS stock solution and the curing agent evenly in a ratio of 10:1;
[0090] (4) Evenly spread 6mL of the above PDMS solution in a plastic petri dish with a diameter of 90mm;
[0091] (5) Heat the above solution in an oven at 80°C, evenly spread PTFE powder before it is fully formed, and continue drying to obtain a PDMS film;
[0092] (6) Paste conductive copper foil on the back of printing paper, PI film, aluminum foil, PET film and PDMS film...
Embodiment 3
[0096] Assembling the fish gelatin film and the PDMS film without surface treatment into a triboelectric nanogenerator specifically includes the following steps:
[0097] (1) Dry the discarded fish scales in the sun and wash them with tap water to remove any visible dirt;
[0098] (2) Treat the dried fish scales with 0.1M sodium hydroxide (pH=12) for 1 h. The treated fish scales were washed with tap water until the pH value dropped to about 7.5; then treated with 10% hydrochloric acid for 1 hour to remove minerals. Simultaneously rinse with tap water until the pH drops to around 7.5 again;
[0099] (3) Put 500 mL of water and the treated fish scale into a stainless steel airtight container for hydrolysis, the hydrolysis temperature is 80° C., and the hydrolysis time is 8 hours.
[0100] (4) Use a sieve to separate the solid from the liquid. The liquid filtrate was centrifuged at 2500rpm for 15 minutes to remove any solid residues that may exist in the liquid;
[0101] (5) ...
