Embodiment 1
[0026] Example 1 A method for preparing composite glass fibers with a nano-micron multi-level structure specifically includes the following preparation steps:
[0027] (1) Graphene oxide solids were prepared by the Hummers method reported in the literature, and a 0.5 mg / mL graphene oxide solution was prepared by means of an ultrasonic cell disruptor;
[0028] (2) Use a pipette gun to measure 500 μL of polydiallyldimethylammonium chloride into 200 mL of secondary water, and ultrasonically disperse it in the secondary water;
[0029] (3) Weigh 10 g of chopped glass fiber and add it to the solution obtained in step (2), place it in a water bath shaker at 20°C for 24 hours, and then wash it with secondary water;
[0030] (4) Add 150 mL of the graphene oxide solution prepared in step (1) to the product obtained in step (3), and react for 12 h in a shaking environment; wash the product with secondary water; place the washed product in After drying in a vacuum drying oven at 50°C, p...
