How to achieve the performance of nanographene modification?

Time: 2019-10-24 09:17 Author: admin Hits: Times

Now, nanographene modified materials have penetrated into many fields, and the popular field is the application of electrode materials. Two-dimensional nanoscale materials with only one carbon atom thickness due to their excellent properties. How to achieve the performance of nanographene modification?

The preparation method of graphene has been continuously improved, the problems of preparation technology have been overcome, the mass production has been guaranteed, and it has been widely used.

There are resins and graphene for preparing composite materials, and the resin materials are widely used organic materials. The application of resin and graphene composite materials will affect the resin material market.

The properties of this composite material are much stronger than pure resin materials. Epoxy resin is a commonly used thermosetting resin and is widely used in polymers.

Nanographene modification

In matrix composites, due to its excellent mechanical properties, abrasion resistance, and chemical stability. In addition, epoxy resin has the characteristics of low shrinkage, low cost, easy processing and molding, which makes it widely used in the fields of machinery, chemical industry and aerospace. If used in combination with graphene materials, it will improve the industry level.

Identify raw materials such as graphite oxide, sodium borohydride, anhydrous sodium carbonate, anhydrous p-aminobenzenesulfonic acid, sodium nitrite, hydrated wells, etc. Mixtures are prepared in different proportions and mixed liquids are prepared, and then the sulfonic acid-modified graphene material is processed through various equipment such as a centrifugal separator, an ultrasonic cleaner, and the like.

After the sulfonic acid-modified graphene material is extracted and put into use, the epoxy material is processed after the completion. The raw materials are mainly the following two types: bisphenol A epoxy resin, modified amine curing agent and post-raw material. Be disposed of. It is prepared by stirring and mixing with sulfonic acid-modified graphene, and by various methods such as vacuum and ultrasonic pulverization.

The prepared material samples were observed and tested. Compared with pure epoxy resin, the material properties were greatly improved. The increased hardness and stiffness of the material can meet the application in related fields.
