Embodiment 1
[0031] A preparation method for enhancing the interface performance of basalt, specifically comprising the following steps:
[0032] Step 1. Put the basalt fiber in absolute ethanol for ultrasonic cleaning for 30 minutes, then wash it with deionized water until the supernatant liquid is neutral, put it in a 40°C oven and dry it for 6 hours to obtain the cleaned basalt fiber;
[0033] Step 2, mixing PAN as the solute of the spinning solution and the solvent N,N-dimethylformamide to obtain a spinning solution, the mass concentration of the spinning solution is 6%;
[0034] Step 3. Use a syringe to extract 6ml of the spinning solution, use the cleaned basalt fiber as the core layer, and prepare PAN-basalt nano-coated fiber by electrospinning. The ambient temperature of the electrospinning is 20±2°C, The relative humidity is 60±5%;
[0035] Specifically, in step 3, follow the steps below:
[0036] Step 3.1: Place the cleaned basalt fiber 3 as the core layer about 1 mm above the ...
