Abstract
AbstractFlexible organic light emitting diodes (FOLEDSs) require a barrier layer with transparency, thermal stability, and flame retardance to prevent water from inducing the corrosion of electrode and ultimately deterioration. Herein, HPS spheres were incorporated into the vinylidene chloride‐methyl acrylate (VDC‐MA) matrix to enhance the water vapor barrier property, thermostability, and anti‐glare effect. Scanning electron microscopy showed that HPS spheres were more compatible with VM (89.86‐10.14) by presenting better water vapor barrier property rather than with VM (92.38‐7.62). The anti‐glare effect of composite film was improved with HPS spheres, while the transparency still maintained over 80%. Thermogravimetric analysis showed that the weight loss still maintained over 50% with the incorporation of HPS spheres, indicating significant improvement compared with control VDC‐MA films. Our research supplies an effective approach to prepare transparent and flame retardant hybrid films with enhanced water vapor barrier, thermostability, and anti‐glare properties, which is promising in the encapsulation of FOLEDSs and other electronics areas.
