specific Embodiment approach 1
[0016] Embodiment 1: The method for surface modification of materials combined with plasma and chemical methods in this embodiment is carried out in the following steps:
[0017] 1. Plasma activation treatment: 1g~100g of material is placed in a plasma processor for treatment;
[0018] 2. Preparation of benzophenone hydrazone derivatives: Add 2g to 20g of benzophenone derivatives into a container, add 50mL to 1000mL of absolute ethanol and 1g to 50g of hydrazine hydrate with a mass fraction of 85% in turn, and stir Reflux reaction for 1d to 5d; then use the vacuum distillation method to concentrate the ethanol in the reaction solution, cool and crystallize the remaining reaction solution in an ice-water bath for 10min to 60min, filter the product under reduced pressure with a sand core funnel, and wash with distilled water for 3~ 5 times. After vacuum drying, the benzophenone hydrazone derivatives are obtained.
[0019] 3. Preparation of bisaryldiazomethane derivatives: Take...
specific Embodiment approach 2
[0022] Embodiment 2: This embodiment is different from Embodiment 1 in that the material described in Step 1 is a polymer material or an inorganic non-metallic material. Other steps and parameters are the same as those in the first embodiment.
specific Embodiment approach 3
[0023] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the material described in step 1 is a carbon material. Other steps and parameters are the same as those in Embodiment 1 or 2.
