Examples
Embodiment 1
[0048] 1) Solution configuration;
[0049] Use a graduated cylinder to measure the Nafion solution 40ml and 10ml of dimethylacetamide (DMAC) with a mass fraction of 5% to mix, and magnetically stir and heat to concentrate until the concentration of Nafion is 40%;
[0050] 2) Planix gel configuration;
[0051] Weigh 4g of F-127 white powder, dissolve it in 6g of water, use a planetary mixer to stir evenly into a transparent gel, use a print head for preliminary inspection, the gel can be extruded into a uniform filament;
[0052] 3) Composite printing process;
[0053] S301, first load the ion polymer ink and F127 gel into the direct-writing printer with double nozzles, and adjust the extrusion air pressure for printing the ion polymer ink and F127 respectively, so that the nozzles can evenly discharge filaments;
[0054] S302, run the G code of the array model, the printer parameters are set to a layer thickness of 0.25mm, a scanning speed of 35mm / s, and an extrusion pressur...
Embodiment 2
[0060] 1) Solution configuration;
[0061] Use a graduated cylinder to measure 20ml of Nafion solution and 10ml of dimethylformamide (DMF) with a mass fraction of 5% and mix it with magnetic stirring, heating and concentrating until the concentration of Nafion is 60%.
[0062] 2) Planix gel configuration;

[0074] 2) Planix gel configuration;
[0075] Weigh 3g of F-127 white powder, dissolve it in 7g of water, use a planetary mixer to stir evenly into a transparent gel, use a print head for preliminary inspection, the gel can be extruded into a uniform filament;
[0076] 3) Composite printing process;
[0077] S301, first load the ion polymer ink and F127 gel into the direct-writing printer with double nozzles, and adjust the extrusion air pressure for printing the ion polymer ink and F127 respectively, so that the nozzles can evenly discharge filaments;
[0078] S302, run the G code of the array model, the printer parameters are set to a layer thickness of 0.2mm, a scanning speed of 15mm / s, and an extrusion pressure of 0....
