specific Embodiment approach 1
[0025] Specific implementation mode one: the preparation method of the inner filler of the ultra-light thermal clothing in this embodiment is implemented according to the following steps:
[0026] 1. Preparation of graphene oxide: Add natural flake graphite into strong oxidizing mixed acid, stir for 10min-60min at a stirring speed of 100r / min-800r / min, then add strong oxidant permanganate in 3-10 times Potassium to prepare mixture A, then put mixture A in a water bath at 30°C to 80°C, and stir at a constant temperature for 4h to 20h at a stirring speed of 200r / min to 800r / min to obtain mixture B, and then mix mixture B Adding it into ice water, and adding hydrogen peroxide with a mass fraction of 30% to the ice water to obtain a graphite oxide suspension, washing with suction, centrifugal washing and drying, to obtain graphene oxide;
[0027] 2. Preparation of graphene oxide dispersion: Add the graphene oxide obtained in step 1 into deionized water and stir evenly to obtain a ...
specific Embodiment approach 2
[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the mass ratio of the volume of the strong oxidizing mixed acid described in step 1 to the natural flake graphite is (10mL-400mL): 1g. Other parameters are the same as in the first embodiment.
specific Embodiment approach 3
[0037] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the strong oxidizing mixed acid described in step one consists of phosphoric acid with a mass fraction of 10% to 85% and sulfuric acid with a mass fraction of 10% to 98% by volume Ratio (3~10):1 composition. Other parameters are the same as those in Embodiment 1 or 2.
