Core Innovations in Dispersion Techniques
- The use of a low pressure system with a vacuum chamber and a vacuum pump system, as well as a process container that can be rotated, moved, or vibrated. the process further includes allowing a primary gas stream with a variable or pulsed flow rate to enter the vacuum chamber, along with allowing at least one secondary gas stream with a variable or pulsed flow rate. the power source used in the process can be a low pressure system or a separate load lock chamber, and the working pressure can be adjusted by changing the flow rate of the primary gas stream or by using a combination of the vacuum pump system and the power source. the surface of the particles is exposed to a reactive gas or reactive energetic species formed by the interaction of the plasma with reactive precursors, resulting in particles with a modified surface energy. the modified surface energy can be used to improve the dispersion of particles in a liquid or flowable medium. the process can be used to modify the surface energy of particles in a continuous or batch process, and the collected particles can be used in various applications, such as in the coating of surfaces or in the production of materials.
