| Abstract Scope |
Encapsulation is a key aspect to the long-term function of an electrophoretic nanoparticle display (EPD). However, the assembling process is complicated by the solvents used to suspend the particles. For polar solvents, few polymers are both chemically compatible and conformable to the encapsulant materials.
In this work, a variety of polar solvents and sealants were studied to increase the stability and lifetime of our displays beyond just the few cycles as shown in literature. Metrics including chemical compatibility, insulation resistance, and adhesion were investigated. Herein we demonstrate a polar solvent and sealant combination that extends the display lifetime to at least 2 weeks. The successful long-term sealing of the nanoparticle suspension is imperative to display function over time and can lead to next-generation full-color reflective electronic displays.
Work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-ABS-850937. |
