The impact of CeO2 nanospheres doping on the electro-optical properties of progressive driving triple-layer PDLC devices

In this manuscript, the triple-layer PDLC device with progressive driving function was prepared by integrating three single-layer PDLCs with different electro-optical properties. In comparison with conventional single-layer PDLC, triple-layer PDLC is capable of achieving controllable transmittance by regulating the applied voltage under low-voltage conditions. The optimal ratio and polymerisation conditions were explored by introducing oleic acid modified CeO2 nanospheres and adjusting the polymerisation temperature as well as the UV light intensity. It was found that the polymer network morphology was affected by CeO2 nanospheres content, polymerisation temperature, and UV intensity, which led to changes in the electro-optical properties of the triple-layer PDLC. The samples obtained under the optimal ratio and process conditions exhibited a 77% acceleration in rise response time (ton) compared to the original conditions, while still maintaining excellent progressive driving performance. Its potential for application in the field of intelligent display windows has been significantly enhanced by these advantages.
