Methods and systems for monitoring and controlling surfactant concentration in liquid crystal colloidal dispersions |
| abstract |
There are provided methods and systems for precisely controlling the surfactant concentration and character of ferroelectric nanoparticles in a ferroelectric liquid crystal dispersion. In an aspect, the invention provides an efficient FTIR technique to characterize the status and measure the distribution of the surfactant in ferroelectric particle dispersion. This allows for establishing a reproducible fabrication process for ferroelectric nanoparticle liquid crystal dispersions. The methods also maintain the nanoparticles ferroelectricity, which is provided by the addition of surfactant during a comminution process. The invention therefore optimizes both the milling time (to achieve small particle size and narrow size distribution) and surfactant concentration (to maintain the ferroelectricity during milling). |
