Yunus Emre Çetin The best way to convert graphene oxide flakes to powder form for use in polyester resin is by using a high-energy ball milling process. This process uses mechanical energy to reduce the particle size of the flakes, resulting in a fine powder. Other methods such as air-jet milling, or spray drying may also work, but ball milling is the most commonly used method.

I understand you, but we will use very little amount graphene oxide. Even so do you think that ball milling will work efficiently ?

Yunus Emre Çetin Ball milling may still be a viable option for reducing the size of small quantities of graphene oxide flakes, but it is important to note that ball milling can be time-consuming and may require specialized equipment. Additionally, ball milling may result in uneven particle size distribution, which can impact the performance of the graphene oxide in the polyester resin. Other methods, such as high-pressure homogenization or ultrasonic treatment, may be more efficient in reducing the particle size of small quantities of graphene oxide. However, it is recommended to experiment with different methods to determine the best approach for your specific application, taking into consideration the properties of both the graphene oxide and the polyester resin.

You can also use a nano ball mill to reduce the size of graphene oxide flakes into a powder form. Nano ball mills, also known as planetary ball mills, are capable of producing fine and uniform powders due to the high energy of the grinding balls. They are commonly used in the production of nanoparticles and have been applied in various fields, including materials science and engineering, pharmaceuticals, and biotechnology. When using a nano ball mill, it is important to properly choose the grinding conditions, such as ball size, grinding time, and speed, to obtain the desired particle size and distribution. Additionally, it is recommended to add a dispersant to the graphene oxide flakes to aid in the dispersion and prevent aggregation during the milling process.
