The major objective of this project is to exfoliate graphite into graphene by using ultrasonic assisted liquid-phase exfoliation method, and to apply the produced graphene on fabricating nanopolymers.

- Manufactured high power density ultrasonic device which has the maximum power of 1.6kW/litter for exfoliating graphite into graphene.
- Experimented processes of exfoliating graphite into graphene by using the manufactured device, the produced graphene has 2,5µm in size and thickness less than 20nm, these were measured by using FE-SEM electronic microscope and Raman spectroscopy.
- Researched on reinforcing graphene material for natural rubber, the result showed that graphene at small content from 0.5% to 1% can increase features of base rubber, at higher levels of content, material features tend to decrease. Meanwhile if graphene surface is processed by 4% aminsilan, the produced nanocomposite’s features will be increased in correlation with the graphene content from 0-5%, this is higher than the case in which the surface is not processed at the corresponding content.
- Applied graphene for testing purpose on some polymer and composite fields including: nanopolymer reinforcing graphene cooling cream, electrodeposited nickel-graphene nanocomposite coating.

The project creates a potential technology development in exfoliating graphite into graphene which is more efficient and gives better quality, and more suitable for development conditions in Vietnam.
