Embodiment 1
[0048] This embodiment provides a method for preparing an electrostatically loaded polyester woven fabric material with a bonding layer, a conductive layer and an electrical storage layer. The specific steps are as follows:
[0049] Step 1: Combine layer generation:
[0050] a) Pre-cleaning: wash 300-mesh polyester woven fabric twice in pre-cleaning bath acetone (analytical pure) to remove surface impurities, and then dry naturally at room temperature for 15 minutes;
[0051] b) Preparation of dopamine treatment bath: prepare a buffer solution with a concentration of 10 mM tris-HCl (Tris-HCl), adjust the pH to 8.5; add dopamine hydrochloride and stir to dissolve, and prepare a concentration of 2 g / L dopamine hydrochloride solution treatment bath;
[0052] c) Bonding layer formation: place the pre-cleaned 300-mesh polyester woven fabric in a dopamine hydrochloride solution treatment bath at 30°C with a solid-to-liquid ratio of 1:2, treat it for 30 minutes, wash it in three wat...
Embodiment 2
[0061] This embodiment provides a preparation method of a silver polyester blended woven fabric material with a binding layer, a conductive layer and a storage layer for electrostatic loading, and the specific steps are as follows:
[0062] Step 1: Combine layer generation:
[0063] a) Pre-cleaning: wash the silver polyester blended woven fabric three times in deionized water in the pre-cleaning bath to remove surface impurities, and then dry naturally at room temperature for 10 minutes;
[0064] b) Preparation of dopamine treatment bath: prepare a buffer solution with a concentration of 15mM Tris-HCl, adjust the pH to 8.5; add dopamine hydrochloride and stir to dissolve, and prepare a concentration of 3g / L dopamine hydrochloride solution treatment bath;
[0065] c) Bonding layer generation: place the pre-cleaned silver polyester blended woven fabric in a dopamine hydrochloride solution treatment bath at 40°C with a solid-to-liquid ratio of 1:3, treat for 40 minutes, wash in ...
