Embodiment 1
[0021] Synthesis of polyacid-doped polyaniline / silver nanoribbon composites:
[0022] Do this in an 80ml glass container. Use a pipette to remove 0.1 ml of aniline liquid, 0.040-0.10 g of silver nitrate and 0.3-0.4 g of H 4 SiW 12 o 40 The acid was dissolved in 40 ml of deionized water and stirred well. Then add 0.3-0.4 grams of ferric nitrate into the above solution, stir quickly and evenly, and then put it into the freezer of the refrigerator at -10°C-18°C for polymerization. After the product turns from light yellow to dark green, thaw the product, filter the resulting dark green product, wash with distilled water and absolute ethanol multiple times to remove impurity ions and oligomers, and vacuum dry it in a vacuum oven at 50°C for 24 hours. use.
[0023] To the characterization of embodiment 1 complex:
[0024] (1) Scanning electron microscope to characterize the product form
[0025] It was observed with a Hitachi XL-30ESEM FEG scanning electron microscope with a...
Embodiment 2
[0039] Synthesis of polyacid-doped polyaniline / silver nanoribbon composites:
[0040] Do this in an 80ml glass container. Use a pipette to remove 0.1 ml of aniline liquid, 0.04 g of silver nitrate and 0.4 g of H 4 SiW 12 o 40 The acid was dissolved in 40 ml of deionized water and stirred well. Subsequently, 0.4 g of ferric nitrate was added to the above solution, stirred quickly and evenly, and then put into the freezer of the refrigerator at -10°C for polymerization. After the product turns from light yellow to dark green, thaw the product, filter the resulting dark green product, wash with distilled water and absolute ethanol multiple times to remove impurity ions and oligomers, and vacuum dry it in a vacuum oven at 50°C for 24 hours. use.
[0041] Characterization: Same as Example 1.
Embodiment 3
[0043] Synthesis of polyacid-doped polyaniline / silver nanoribbon composites:
[0044] Do this in an 80ml glass container. Use a pipette to remove 0.1 ml of aniline liquid, 0.06 g of silver nitrate and 0.4 g of H 4 SiW 12 o 40 The acid was dissolved in 40 ml of deionized water and stirred well. Subsequently, 0.3 g of ferric nitrate was added to the above solution, stirred quickly and evenly, and then put into the freezer of the refrigerator at -18°C for polymerization. After the product turns from light yellow to dark green, thaw the product, filter the resulting dark green product, wash with distilled water and absolute ethanol multiple times to remove impurity ions and oligomers, and vacuum dry it in a vacuum oven at 50°C for 24 hours. use.
[0045] Characterization: Same as Example 1.
