Conclusions

Polymer dispersions offer high promise for new types of electrooptic and nonlinear optic materials. The materials science problems involved in these materials are both challenging and fascinating as well as limitless. They illustrate the need for a better fundamental understanding of the effects of surfaces and finite size on liquid crystal materials. Many practical problems lie ahead: lowering the threshold voltage while increasing the resistivity for active matrix technologies; broadening the temperature range and improving environmental stabilities; creating different operation modes such as reverse mode; incorporating bistability; improving the materials for infrared shuttering for applications in solar control and IR cameras. Polymer dispersions are the beginning of a new science in optical materials with a promising future.
