Polymer-stabilized liquid crystal (PSLC) dimming film has attracted widespread attention due to its normally transparent state, energy-saving capability, and excellent electro-optical performance, which promising applications in smart cars building windows. However, achieving good performance high peel strength simultaneously still remains challenging. In this study, a PSLC based on monoepoxy diepoxy monomers was prepared through rapid cationic polymerization, showing low driving voltages simultaneously. The influence of the content composition two epoxy microstructures, mechanical properties, films were systematically studied. polymer morphology could be effectively modulated by doping monomers. with total monomer ≤15 wt% showed enhanced properties when lateral networks denser substrate. When ratio E6M E6PM 12:3, compared pure E6M, threshold voltage decreased from 18.2 V 12.6 V, increased 62.53 kPa 136.37 kPa. These can adapt requirements different application scenarios changing proportion monomers, strategy prospects actual production films.
