Embodiment 1
[0029] Embodiment 1: Silver behenate crystal morphology detection process
[0030] (1) Prepare a mixed solution of silver behenate crystals with a concentration of 50g / L. The solvent of the mixed solution is acetone, methyl ethyl ketone, and isopropanol according to the volume ratio of 0.7:0.9:1. After ultrasonic dispersion, centrifuge for 1min, and its rotating speed is 5000rpm. Discard the supernatant;
[0031] (2)Use absolute ethanol to ultrasonically disperse the sample treated in step (1), centrifuge for 1min at a speed of 5000rpm, and discard the supernatant;
[0032] (3) Add a concentration of 30g / L fluorine-containing surfactant solution to the sample treated in step (2), after ultrasonic dispersion, drop the sample on a copper grid coated with a Formova film, dry it under a 250W infrared lamp, Gold was plated in the sputtering apparatus to increase the conductivity for easy observation, the purity of the gold target was 99.999%, and the coating was 25mA for 40s.
