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.

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.

Abstract

The invention discloses a material surface modification method by combination of plasmas and a chemical method, relates to the technical field of material surface treatment, in particular to a method of performing modification treatment on a material surface by cooperatively utilizing the plasmas and the chemical method, and aims to solve the problem that a material subjected to plasma method surface treatment is low in shear strength. The material surface modification method is characterized in that surface activating treatment is performed on the material by the plasmas, and material surface modification is realized by insertion reaction through utilizing carbyne and the groups such as C-H, O-H and N-H which are inherent in the material and are introduced by plasma treatment. A surface-modified carbon fiber interface prepared by the method has higher shear strength than that of a non-modified carbon fiber interface, and the reaction activity and efficiency of a chemical grafting method are improved, so the surface functional modification degree can be improved. The method is suitable for material surface treatment and enhances the performance of the material.

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a method for modifying the material surface by synergistically utilizing plasma and chemical methods. Background technique [0002] In the use and processing of materials, surface properties often have a great impact on their performance. The surface properties of materials depend to a large extent on the type and quantity of active functional groups, surface morphology and structure, etc. For example, in the field of composite materials, if the surface of the reinforced material is inert, the affinity between the reinforcement and the substrate in the obtained composite material will be weak, which will further cause the load to be unable to be effectively transmitted between the reinforcement and the substrate, and high performance composites. Therefore, in order to strengthen the connection between the reinforcement and the base material, it is usually nec...
