Cavitation Superiority
For flexible hybrid electronics, wearable electronics, thermal management and aerospace coatings
Comparison of Tools and Processes
Comparison of ACI’s cavitation process provides numerous benefits over other mixing technologies, resulting in better dispersion and better quality, all in a simplified process that does not affect primary particle morphology. Importantly, the cavitation process disperses the solid phases directly into final formulations, even for high viscosity pastes exceeding 200,000 cps. Additional benefits and comparison to other mixing technologies are provided below.
Comparison of Tools and Processes
The superior dispersion and elimination of agglomerates achieved with the ACI cavitation process can be seen in the SEM micrographs and particle size distributions below. The micrographs show a range in particle size, shape, and composition, including carbon nanotubes, micron-sized silver powder, and sub-micron fumed silica. The agglomerates evident in the raw material micrographs are eliminated resulting in the more uniform material revealed in the post cavitation images.
Particle Size Distribution Case Studies
The cavitated particle size distributions of the silver, fumed silica, and micron-sized graphene are compared to a 3 roll mill in the first set of graphs below. In all cases, the agglomerate elimination still evident after milling is removed when the material is cavitated, which lowers the effective particle size and tightens the distribution. This effect is more dramatic when the particle size of as-received material is compared to cavitated material. As shown in the final set of graphs, the mean particle size of both nanosilver and graphene drops by orders of magnitude following dispersion with the ACI cavitation process.
